What is the maximum area of a rectangular yard that can be enclosed with 120 m of fencing
in each case?
a. The yard is enclosed on all four sides.
b. The yard is enclosed on three sides.
+285 For a)
you have 120 m of fencing. you divided that by the 4 sides you have to enclose. This gives you 30m. to find the area you multiply length x heights so 30m x 30m = 900 square meters.
120/4=30 30x30=900
for b)
you have the same amount of fencing but only 3 sides, so in this case you take 120/3= 40.
40 m x40 m=1600 square meters
