Calculate the area of the rectangle.

Video Solution

Solution Steps

00:00 Calculate the rectangle's area
00:03 We'll use the formula for calculating rectangle area (side times side)
00:07 We'll substitute appropriate values according to the given data and solve for the area
00:20 Let's break down 1.5 into 1 and a half
00:23 Let's properly expand the brackets - multiply each factor
00:32 Calculate each multiplication and then sum up
00:40 And this is the solution to the problem

Step-by-Step Solution

Let's begin by solving the first exercise:

32=9 3^2=9

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

9×1.5=13.5 9\times1.5=13.5

Answer

13.5
