Answer:
A = 322 ft²
Step-by-step explanation:
the area (A) of a trapezoid is calculated as
A = [tex]\frac{1}{2}[/tex] h (b₁ + b₂ )
where h is the perpendicular height between the bases and b₁, b₂ the bases
here h = 14, b₁ = 35 , b₂ = 11 , then
A = [tex]\frac{1}{2}[/tex] × 14 × (35 + 11) = 7 × 46 = 322 ft²
