Answer:
The height of the trapezoid is 4ft
Step-by-step explanation:
First of all, to solve this problem we need to use the area formula of a trapezoid:
A = area = 20ft²
b1 = base 1
b2 = b2
h = height
b1 + b2 = 10ft
A = ½ (b1+b2) * h
we replace with the known values
20ft² = ½ (10ft) * h
20ft² = 5ft * h
20ft² / 5ft = h
4ft = h
The height of the trapezoid is 4ft
