Mathematics can be a really challenging subject for a lot of students, whether they are in primary school, elementary or even high school. If we suppose a rectangle has length as a and width as b. To find the area of a rectangle, you need to multiply the length by the width of the rectangle. It is the amount of the two-dimensional space a shape occupies.įor instance, the area of a rectangle is the amount of surface enclosed by the sides of the rectangle. The area is a two-dimensional concept that gets measured by square meters ². The perimeter is the distance around a two-dimensional shape whereas the area is the measurement of the space inside the shape. The perimeter for this field is P = 2x(20+13) = 66 m What is the difference between area and perimeter? Therefore, the perimeter of this rectangle is P = 2x(12+5)= 34 cmĪ rectangular field is 20 m long and 13 m wide. We know that the perimeter of a rectangle is P = 2x(sum of adjacent sides) One side of a rectangle is 12 cm and the other one is 5 cm. The perimeter of this rectangle is P = 7+7+3+3 = 2x(7+3)= 20 cm The length and width of the rectangle are 7 cm and 3 cm, respectively. mm, cm, meters, km, or in, ft, yd, miles. Make sure the calculation is done using the same unit - the result will also be in that unit, e.g. Here are some examples of how to calculate the perimeter of a rectangle: The formula for the perimeter of a rectangle is (width + height) x 2, as seen in the figure below: This is the equivalent of adding all four sides, since opposite sides are of equal length by definition. How do you calculate the perimeter of a rectangle? Hence, the formula for the perimeter of a rectangle is 2 x (sum of adjacent sides). Since the parallel sides of a rectangle are always equal, you only need to find the length of two sides in order to find the perimeter of the rectangle. To calculate the perimeter, you simply have to add up the side lengths of the rectangle. Meaning that you have to add the lengths of its sides to find its perimeter. The perimeter of a rectangle is the total length of its figure, known as the sum of the length of all the sides of the rectangle. All of its angles are right angles (90°) and its opposite parallel sides are always of equal length. It’s a shape that you will come across a lot so it’s important you know how to calculate its perimeter and area.Ī rectangle is a four-sided polygon. In mathematics, you will come across many different shapes and sizes like squares, circles, polygons…and you will be asked to calculate their perimeter or even their volume.
