First, we can take a look at the given parallelogram.

Now, we can recall that the area of a parallelogram is the product of its base and its height. A=bh Let's identify the base and the height of the parallelogram on the diagram!

In the given parallelogram, the base is 20 inches and its corresponding height is 25 inches. Let's substitute these values into the formula for the area of a parallelogram and simplify.

A=bh

SubstituteII

b= 20, h= 25

A= 20( 25)

Multiply

A=500

The area of the parallelogram is 500 square inches.

Now, we can recall that the area of a parallelogram is the product of its base and its height. A=bh Let's identify the base and the height of the parallelogram on the given diagram!

In the given parallelogram, the base is 10 millimeters and its corresponding height is 8 millimeters. Let's substitute these values into the formula for the area of a parallelogram and simplify.

A=bh

SubstituteII

b= 10, h= 8

A= 10( 8)

Multiply

A=80

The area of the parallelogram is 80 square millimeters.
