Answer 1

A = 72 units²

Explanation:

the area (A) of a trapezoid is calculated as

A =
`(1)/(2)` h (b₁ + b₂ )

where h is the perpendicular height between the bases b₁ and b₂

note that the middle section of the lower base = upper base = 6

here h = 8 , b₁ = 3 + 6 + 3 = 12 , b₂ = 6 , then

A =
`(1)/(2)` × 8 × (12 + 6) = 4 × 18 = 72 units²
