Answer:
37.5
Step-by-step 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
