Question

The length of the parallel sides of a trapezium are 3cm and 1 cm, and the distance between them is 1 cm. What is its area?​

Answer 1

A = 2 cm²

Explanation:

The area (A) of a trapezium is calculated as

A =
`(1)/(2)` h (b₁ + b₂ )

where h is the distance between parallel sides and b₁, b₂ , the parallel sides

Here h = 1, b₁ = 3, b₂ = 1 , then

A =
`(1)/(2)` × 1 × (3 + 1) =
`(1)/(2)` × 4 = 2 cm²
