The area of a rectangular vegetable garden is 216 square feet. If the length is 12 feet,
what is the perimeter of the garden?
step 1
Find the width of the rectangular garden
we have that
A=L*W
we have
A=216 ft2
L=12 ft
substitute
216=12*W
solve for W
W=216/12
W=18 ft
step 2
Find the perimeter
P=2(L+W)
substitute
P=2(12+18)
P=60 ft
