The top surface of a desk is composed of 2 rectangles and a triangle. Some side lengths of the top surface of the desk are shown. 1.5 ft 1 1 1 1 1 2.5 ft 1.5 ft What is the area of the top surface of the desk in square feet?

8.625 ft²

Explanation:

CHECK THE FIGURE AT THE ATTACHMENT

We can start by determining the area of the first rectangle which is

(1.5 x 2.5 )

= 3.75ft²

We can determining the area of the second rectangle which is

(1.5 x 2.5)

= 3.75ft²

We can determining the are of the given triangle which is

(1.5 x 1.5 )/2

= 1.125ft²

the area of the top surface of the desk in square feet can be determining by adding all the areas together

( 3.75 + 3.75 + 1.125)

= 8.625 ft²

Hence, the area of the top surface of the desk in square feet is 8.625 ft²
