Answer:
96 ft²
Step-by-step explanation:
The formula of an area of a trapezoid:
[tex]A=\dfrac{b_1+b_2}{2}\cdot h[/tex]
[tex]b_1,\ b_2[/tex] - bases
[tex]h[/tex] - height
We have:
[tex]b_1=10ft+4ft=14ft\\\\b_2=10ft\\\\h=8ft[/tex]
Substitute:
[tex]A=\dfrac{14+10}{2}\cdot8=\dfrac{24}{2}\cdot8=(12)(8)=96\ ft^2[/tex]
