Answer:
8.625 ft²
Step-by-step 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
