Question

Richard has a rectangular plot of land that is 525 feet long and y feet wide. He decides to build a fence around the plot. If the perimeter of the plot is 1,504 feet, find the value of y

Answer 1

The perimeter of the figure or polygon is calculated by adding up the value of the sides. In this case,
 
           Perimeter = 2 (length + width)

We are given that the length is equal to 525 ft.
           1205 = (2)(525 + y)

The value of y from the equation is 77.5 ft. 

Answer: 77.5 ft
