Answer:
A = 37.5 in²
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 = 10 , b₁ = 5 and b₂ = 2 [tex]\frac{1}{2}[/tex] = 2.5 , then
A = [tex]\frac{1}{2}[/tex] × 10 × (5 + 2.5) = 5 × 7.5 = 37.5 in
