Question

A yard is in the shape of a trapezoid.

A trapezoid with base lengths of 11 yards and 14 yards, and height 18 yards.

What is the area of the yard?

225 yd2
450 yd2
1,386 yd2
2,772 yd2

Answer 1

A = 225 yd²

Explanation:

the area (A) of a trapezoid is calculated as

A =
`(1)/(2)` h (b₁ + b₂ )

where h is the height between the bases b₁ and b₂

here h = 18 , b₁ = 11 , b₂ = 14 , then

A =
`(1)/(2)` × 18 × (11 + 14) = 9 × 25 = 225 yd²
