Answer:
190ft

Explanation:

Side a= 110ft

Side b= ?

Height= 75ft

Area=
11,250ft^2


A=(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


(2A)/(h)=a+b

Subtract a


(2A)/(h)-a=b

Now plug in your values.


b=(2A)/(h)-a


b=(2(11,250ft^2))/(75ft)- 110ft


b=(22500ft^2)/(75ft)- 110ft


b=300ft- 110ft


b=190ft
