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. What is the area of the top surface of the desk in square feet?

Answer
8.625 ft²
Step-by-step explanation:
first you find the area of the first rectangle. this equation would be 1.5 x 2.5 = 3.75
Next, you would find the area of the 2nd rectangle. This equation is 1.5 x 2.5 = 3.75
Now, you have to find the are of the triangle. This equation is 1.5 x 1.5 = 2.25 ÷ 2 = 1.125
Lastly, you add all of the numbers together. 3.75 + 3.75 + 1.125 = 8.625
