Divide both numbers by 2 to get 3/4 degrees per 30 mins.

Now, multiply both numbers by 3 to get 9/4 degrees per 90 mins.

Simplify: 2 1/4 per 1 1/2 hours.

Semenov [28]

The area of a trapezoid is
A = (1/2) h (b1 + b2)
where
h is the height
b1 is length of base 1
b2 is the length of base 2

We are given with the area and assuming that the trapezoid is isosceles, the length of base 1 is
b1 = 4 ft
If the height of the trapezoid is 4.5 feet, it ensures that the shed will fit inside the trapezoid patch of land. Therefore, the height of the trapezoid is 4.5 feet.
