Exercise 7 Page 287

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

14.4km^2

Practice makes perfect

The area of a parallelogram is the product of its base and its height.

Let's rotate the figure to make it easier to identify the base and the height!

After rotating the parallelogram, we can see that the length of the base is 4.8 kilometers and the height is 3 kilometers. Let's substitute these two values into the formula for the area of a parallelogram and simplify.

A=bh

b= 4.8, h= 3

A= 4.8( 3)

Multiply

A=14.4

The area of the parallelogram is 14.4 square kilometers.
