A zoo is being renovated to make it more animal friendly. Originally, the area for zebras, deer, and other 4-legged animals was divided into square pens. The new plan calls for each pen to be 8m longer and 1m wider.

c. If the side of the old pen was 15meter, what will be the area of each new pen?



Let L be the original Length of the square pen
Let W be the original Width

Area for rectangle

A = W x L

Area of square 

A= L x W

L = W

for the new square pens

A = ( L + 8m ) ( W + 1m )

L = W

L = 15

A = (15 + 8) (15 + 1)
A = 368 m²
