Step-by-step explanation:
Answer: Length = 11 feet
Width = 6 feet
Step-by-step explanation:
A rectangle is a four sided shape that has 2 equal lengths,L and 2 equal widths,W
The perimeter of the rectangular piece of land is the total distance around it. It is expressed as
Perimeter = 2L + 2W = 2(L+W)
The perimeter is given as 34ft. It means that
34 = 2(L+W) - - - - - - - -1
The length of the rectangular piece of land is 5ft more than two times its width. It means that
L = W + 5
Substituting L = W + 5 into equation 1, it becomes
34 = 2(W + 5 +W) = 2(2W + 5)
2W + 5 = 34/2 = 17
2W = 17 - 5 = 12
W = 12/2 = 6 feet
L = W + 5 = 6+5
L = 11 feet
