Exercise 38 Page 630

Use the formula for the area of a parallelogram.

About 100.1m^2

Practice makes perfect

Let's consider the given parallelogram.

Triangle

We want to find the area of a parallelogram. We can use the following formula to do it. Area= b h In this formula, b is the length of the base and h is the height. For our parallelogram, we will substitute b= 11.5 for the base and h= 8.7 for the height into the formula to calculate its area.

Area=bh

b= 11.5, h= 8.7

Area=( 11.5)( 8.7)

Multiply

Area=100.05

Round to 1 decimal place(s)

Area≈ 100.1

The area of the parallelogram is about 100.1 square meters.
