Problema Solution
A rectangle area is to be fenced in along a straight river bank as illustrated. the length of the fenced in area is to be 3 feet greater than the width, and the total amount of fencing to be used is 63 feet. find the width and length o the fenced in area
Answer provided by our tutors
Let
x = the width of the fence
x + 3 = the length of the fence
P = 63 ft the perimeter of the rectangular area
Since P = 2*length + 2*width we have:
P = 2(x + 3) + 2x
Now we have the following equation:
2(x + 3) + 2x = 63

........
x = 14.26 ft
x + 3 = 14.25 + 3 = 17.25 ft
The width of the fence is 14.25 ft.
The length of the fence is 17.25 ft.
