1. To solve this problem you must apply the formula for calcúlate the area of a trapezoid, which is shown below:
A=(B+b)h/2
A is the area of the trapezoid (A=24).
B is the larger base of the trapezoid (B=5).
b is the smaller base of the trapezoid (b=5).
h is the height of the trapezoid.
2. You must clear "h" from the formula:
A=(B+b)h/2
2A=(B+b)h
h=2A/(B+b)
3. When you susbtitute the values into h=2A/(B+b), you obtain:
h=2A/(B+b)
h=2(24)/(5+3)
h=48/8
h=6
