Question 1128456: The formula for the area of a trapezoid is A = h(B+b) / 2.
.
The area of the trapezoidal truss, is 24 square meters. Find the height of the trapezoid if one base is 8 meters and the other base is the same as the height.

Let B be the known base of length 8; then b (the other base) and h (the height) are the same.
Set B=8 and b=h in the area formula, knowing that the area is 24, and solve the resulting equation for h.
or
Clearly a negative value makes no sense in the problem, so the height is h=4.
ANSWER: The height is 4 meters.
