Question

Can someone check my answer please and thank you

Answer 1

294 m² is correct

Explanation:

The area (A) of a trapezoid is calculated using the formula

A =
`(1)/(2)` h (a + b)

where h is the height and a, b the parallel bases

here h = 21, a = 21 and b = 7, thus

A =
`(1)/(2)` × 21 × 28 = 294 m²
