Question

What is the answer to this question?

Answer 1

Answer:

A = 16.5 cm²

Step-by-step explanation:

the area (A) of a trapezoid is calculated as

A = $\frac{1}{2}$ h (b₁ + b₂ )

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

here h = 3, b₁ = 7 , b₂ = 4 , then

A = $\frac{1}{2}$ × 3 × (7 + 4) = 1.5 × 11 = 16.5 cm²
