Question

The area of a trapezoid is 100 square feet. The sum of the two bases is 25 feet. What is the height of the trapezoid?

I kept getting 4 but that isn't correct

Answer 1

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 ?
