Answer: 190ft

Step-by-step explanation:

Side a= 110ft

Side b= ?

Height= 75ft

Area= 11,250ft^2

A=\frac{a+b}{2}h

Solve for b. Let's begin by multiplying by 2 to get rid of the denominator.

2A=(a+b)h

Divide by h

\frac{2A}{h}=a+b

Subtract a

\frac{2A}{h}-a=b

Now plug in your values.

b=\frac{2A}{h}-a

b=\frac{2(11,250ft^2)}{75ft}- 110ft

b=\frac{22500ft^2}{75ft}- 110ft

b=300ft- 110ft

b=190ft
