Answer 1

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.

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

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

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

$b=300ft- 110ft$

$b=190ft$
