Question

What is the area, in square meters, of the shaded part of the rectangle below?

5 m
10 m
5 m

Answer 1

37.5

Explanation:

the shaded part forms a trapezoid

we can find the area of the trapezoid itself using the formula

A = (a+b)/2 × h

where a and b = base lengths and h = height

here, we are given that the base lengths are 5m and 10m and the height is 5m

so we have A = (a+b)/2 × h

==> plug in a = 10 , b = 5 and h = 5

A = (10 + 5)/2 × 5

==> add 10 and 5

A = (15)/2 × 5

==> divide 15 by 2

A = 7.5 × 5

==> multiply 7.5 by 5

A = 37.5
