if it require 180 feet of fencing to enclose a rectangular lot of 30 feet wide , how long is the lot. draw figure

Question

it is a word problem and figure is required

 

 

 

Answer 1

The perimeter of a rectangle is given by P = 2 times Length + 2 times Width

 

We are given that P = 180f, and W = 30f

 

so, our equation is 180f = 2L + 2(30f), which becomes 180f = 2L + 60f

 

180f - 60f = 2L

120f = 2L

60f = L
