Answer:

B. 8.625 ft²

Explanation:

The total area is the sum of the areas of the two rectangular sections and the area of the triangular section. The area formulas are ...

A = LW . . . rectangle

A = 1/2bh . . . triangle

Here, the dimensions are such that we can simplify the problem a bit

total area = (1.5)(2.5) +1/2(1.5)(1.5) + (1.5)(2.5)

= (1.5)(2.5 + 1.5/2 + 2.5)

= (1.5)(5.75) = 8.625 . . . . . ft²

The total surface area of the desk is 8.625 square feet.
