Question

Find the area of the un-shaded part. ABCD and EFGH are two rectangles. AB = 10 inches, BD = 8 inches EF = 6 inches FH = 4 inches

Answer 1

56 inches!

Explanation:

Rectangles ABCD and EFGH are concentric, that means that they are almost the same but their sides have a different ratio.

First, lets find the area of EFGH.

1). Area of EFGH = a * b = 4 * 6 = 24 inches

Then we will find the area of ABCD.

2). Area of ABCD = a * b = 10 * 8 = 80 inches.

Now we know the areas of the rectangles, we can find the area of the un-shaded part.

3). Area of ABCD - Area of EFGH = 80 - 24 = 56 inches

So, 56 inches will be your answer.
