Answer:
88 u²
Step-by-step explanation:
The formula for the area of a trapezoid is:
A = [tex]\frac{1}{2}h(b_{1}+b_{2})[/tex] where h = height and [tex]b_{1}[/tex]=length of one base and [tex]b_{2}[/tex]=length of the other base.
Given the measurements in the diagram:
h = 4 units
[tex]b_{1}[/tex] = 17 units
[tex]b_{2}[/tex] = 17 + 5 + 5 = 27 units
Plug them into the equation: A = [tex]\frac{1}{2}[/tex](4)(17 + 27) = 88 units²
