Exercise 8 Page 619

To find the area, calculate the product of the base and the height.

240cm^2

Practice makes perfect

Let's take a look at the given parallelogram.

The area of a parallelogram is the product of its base and its height. In the given parallelogram, we will consider the given side whose length is 20 cm as the base and its corresponding height, which is 12 cm.

We can substitute these two values into the formula for the area of a parallelogram and simplify.

A=bh

b= 20, h= 12

A=(20)(12)

Multiply

A=240

The area of the parallelogram is 240cm^2.
