A yard is 3 times as long as it is wide. 176 feet of fencing is needed to enclose the yard. Find the dimensions of the yard
2 answers:
The perimeter of a rectangle is twice the sum of its side lengths.
P=2(L+W), we are told that L=3W and P=176 so
2(3W+W)=176
2(4W)=176
8W=176
W=22 ft, since L=3W
L=66 ft
So the yard is 22 feet wide and 66 feet long.
P = 2(L + W)
L = 3W
P = 176
176 = 2(3W + W)
176 = 2(4W)
176 = 8W
176/8 = W
22 = W <=== width
L = 3W
L = 3(22)
L = 66 <===length
