Now that you have both areas for rectangle A and B, you can add them to get the total area of the irregular rectangle: The area of rectangle A is more complex, but don’t panic! You need to find length of the top side of rectangle A: The total area is the sum of the area of rectangle A and rectangle B. The second thing to do is extend the shape into a larger rectangle and then subtract the smaller rectangle from it. The first thing to do is to split the irregular rectangle as shown below and find the separate areas and add them together. Here’s an example of an irregular rectangle: There are multiple ways to find the solutions to the area of an irregular rectangle – all of which use the same formula mentioned. Then you sum up all the areas that form the shape. One way to find the area of an irregular shape is to divide it into smaller shapes for which you already have the formula. You may need to locate the area of a shape that is not a regular shape on occasion. How do you find the area of an irregular rectangle? Formula notation: Since width is the short side, in this example it’s 200 cm.Smaller numbers are easier to work with so we will work in meters! The question may specify which unit of measurement the answer should be in, but if not then choose the largest notation: (Millimeters < centimeters < meters < kilometers). Unit of measurements: In this example, the unit of measurement is centimeters (cm) for the width, but the length is in meters (m).Let’s follow the steps we did in the previous example: This question is slightly more complex than the previous one. In this example, width is 13 cm as it’s always the shorter side. Formula notation: You should know which side is the length, and which is the width.Unit of measurements: In this example, the unit of measurement is centimeters (cm) meaning the area of this rectangle will be in centimeters squared (cm2).There are two main things to look out for: Questions and solutions to find the area of a rectangle A rectangle’s perimeter is therefore obtained by using the formula P=2l+2w, where “l” is the rectangle’s length and “w” is its width. Unlike area, the perimeter of a rectangle is found by adding the lengths of its four sides. What is the difference between the area and perimeter of a rectangle? The formula is as follows:Ī = L x W, where A denotes area, L denotes length and W denotes width. Multiply the length by the width to get solutions for surface area of a rectangle. What is the formula to find the area of a rectangle? ![]() The area of a rectangle is obtained by multiplying its length by its width. The unit of length will depend on the unit of area, however the following are common in maths questions:Īrea is a two-dimensional concept with a length and width in maths. The amount of space inside a 2D shape is measured by its area. Unlike length, width refers to the shorter side of a rectangle. Width, quite simply, denotes the measurement between two points. The longest side of an object is its extended dimension or length. It’s used to determine the size of an object or the distance between two points. The length of an object or the distance between two points is measured in length. The term “length” refers to the size of an object or the distance between two points. It’s expressed in squares, such as square centimeters, square meters, and square kilometers. The area of a shape refers to the amount of two-dimensional space it occupies. Calculating the area of a shape or surface is helpful in daily life when you need to know how much paint to buy to cover a wall or how much grass seed to sow a lawn, for example. The area of a shape is a measurement of how much space it contains. A rectangle’s opposite sides are parallel to each other and have the same length.The Pythagorean theorem can be used to calculate the diagonal length. There are two diagonals that cross each other.Through the center, there are two lines of reflectional symmetry: vertical and horizontal.Its sides meet at right angles, making it rectilinear.It is equiangular, meaning that all of its corner angles are 90 degrees.A rectangle is cyclic, which means that all of its corners are connected by a single circle.Rectangles have a lot of interesting characteristics:
