Question 1010761: Kandy and Sunehra decided to fence their rectangle gardens, which are located in their yards. The land inside the fence is bright green.
Part A) Sunehra’s garden has the width of 7y-3y. The non-green area has the length of 7^6+8 meters and the length of the total yard is 8^6+7z. What is the perimeter of Sunehra’s garden?
Part B) Mansia decides to buy Sunehra’s garden. However, she is going to multiply the garden’s total perimeter by 9y. What is the new perimeter?

.
A)
.
W=width=7y-3y=4y
.
Length of garden is length of green area:
L=Length of green area=Total length-length of non-green area
L=%288%5E6%2B7z%29-%287%5E6%2B8%29
L=%28262144%2B7z%29-%28117657%29
L=144487%2B7z
.
P=Perimeter=2(L+W)
P=2((144487+7z)+(4y))
P=288974+14z+8y
ANSWER: The perimeter of Sunehra's garden is 288974+14z+8y.
.
B)
N=New Perimeter=9y(P)
N=9y%28288974%2B14z%2B8y%29
N=2600766y%2B126yz%2B72y%5E2
ANSWER: The new perimeter is 72y%5E2%2B126yz%2B2600766y
