Question

Look at the composite figure below. The rectangle is 15 inches by 7 inches. The two congurent

squares have a side length of 5 inches.
What is the shaded area of the composite figure in square inches?

Answer 1

80 squared inches

Explanation:

you find the area of the rectangle first which is 105

then you take away half of each square from the rectangle for each side so just picture the squares as triangles

base=5in so now you find the area of each triangle which gives you

height=5in 5 * 5 / 2= 12.5 and since you have two,multiply 12.5 by 2

12.5 *2 = 25

now subtract 25 from 105 (105 - 25= 80)

and you get your area =80 sq. in.

Answer 2

Answer: 80 square inches

Explanation:

The rectangle’s area is 105 square inches

Each square had an area of 25 square inches, divide 25 by two to get both triangles (12.5)

Multiply by two (gets 25)

Subtract that from 105 and you get 25
