Fritz plans to fence off a square feed lot and then cross-fence to divide it into four smaller feed lots. If he uses 708 feet of fencing, then how much area will be fenced in?
Answer provided by our tutors
let 'a' be the length of the sides of the square
the fence the square he will need 4a ft fence
the cross fence into 4 smaller feed lots he will nee 2a ft fence
4a + 2a = 708
6a = 708
a = 708/6
a = 118 ft
the area of the square is a^2 = 118^2 = 13924 ft^2 thus
13924 ft^2 will be fenced in.
