The given height of this trapezoid is given to be 4.5m
We have to solve for this by making use of the height of a trapezoid. The height is given as
A = (1/2) h (b1 + b2)
The variables here are
h = height
b1 = lenght at base 1
b2 = length at base 2
If the trapezoid that we have is a isosceles triangle, then base 1 is going to be the same length as that of the first base
b1 = 4 ft is the area. Given that the height has to be at least 4.5feet, then this would ensure that the trapezoid would be able to hold the shed.
Hence the height would begiven as 4.5 ft
