Question

There is a pair of parallel sides in the following shape.

Answer 1

A = 38.5 units²

Explanation:

the figure has one pair of parallel sides and is therefore a trapezium.

the area (A) of a trapezium is calculated as

A =
`(1)/(2)` h (b₁ + b₂ )

b₁ and b₂ are the parallel bases and h the perpendicular height between them.

here h = 7 , b₁ = 5 , b₂ = 6 , then

A =
`(1)/(2)` × 7 × (5 + 6) = 3.5 × 11 = 38.5 units²
