Area of a Rectangle: Applying the formula

Look at the rectangle ABCD below.

Side AB is 6 cm long and side BC is 4 cm long.

What is the area of the rectangle?

Remember that the formula for the area of a rectangle is width times height

We are given that the width of the rectangle is 6

and that the length of the rectangle is 4

 Therefore we calculate:

6*4=24

24 cm²

Given the following rectangle:

Find the area of the rectangle.

Let's calculate the area of the rectangle by multiplying the length by the width:

$2\times5=10$

Look at the rectangle ABCD below.

Side AB is 4.5 cm long and side BC is 2 cm long.

What is the area of the rectangle?

We begin by multiplying side AB by side BC

We then substitute the given data and we obtain the following:

$4.5\times2=9$

Hence the area of rectangle ABCD equals 9

9 cm²

The width of a rectangle is equal to 15 cm and its length is 3 cm.

Calculate the area of the rectangle.

To calculate the area of the rectangle, we multiply the length by the width:

$15\times3=45$
