Answer:

top area = 10.125

Step-by-step explanation:

Formulas used

triangle: base × height / 2

rectangle: base × height

1.5×1.5=2.25

2.25 / 2 = triangle = 1.125

1.5×3=4.5

4.5 × 2 because we have two of the same rectangles.

4.5×2 = both rectangles = 9

add our triangle and rectangles gives our top.

9+1.125 = top = 10.125

explained in sentences:

I found the base and height of my formulas. then used a calculator to help me solve. Which got me the answer of 10.125 when I added area of two rectangles and one triangle.
