Answer:

The height of the trapezoid is $4.5\ ft$

Step-by-step explanation:

we know that

The area of a trapezoid is equal to

$A=\frac{1}{2}(b1+b2)h$

In this problem we have

$A=33.75\ ft^{2}$

$b1=5\ ft$

$b2=10\ ft$

substitute in the formula and solve for h

$33.75=\frac{1}{2}(5+10)h$

$67.5=15h$

$h=67.5/15=4.5\ ft$
