Well I don't know !
Let's slow down, relax, and work it out together.
The formula for the area of a trapezoid is
Area = (1/2) · (height) · (the sum of the bases)
Fill in
the numbers
that we know: 100 sq ft = (1/2) · (height) · (25 ft)
Divide each side
by (25 ft) : (100 sq ft) / (25 ft) = (1/2) · (height)
4 ft = (1/2) · (height)
Multiply each side by 2 : 8 ft = height
So what was the major difficulty ?
Did you forget the (1/2) in the formula ?
