Calculate Rectangle Area: 3² cm Width × 1.5 cm Length

Question

The width of a rectangle is equal to $3^2$ cm and its length is $1.5~$ cm.

Calculate the area of the rectangle.

00:00 Calculate the rectangle's area

00:03 Apply the formula for calculating the area of a rectangle (side x side)

00:07 Substitute in the relevant values according to the given data and proceed to solve for the area

00:20 Break down 1.5 into 1 and a half

00:23 Expand the brackets - multiply each factor

00:32 Calculate each multiplication and then add them together

00:40 This is the solution

Let's begin by solving the first exercise:

$3^2=9$

Now let's multiply the length by the width in order to find the area of the rectangle:

$9\times1.5=13.5$

13.5
