The graph below is on the scale of five and I hope it is helpful.
Perimeter=sum of side lengths...
P=2L+2W
P=2(L+W), in this case L and W are 30 and 40 so
P=2(30+40)
P=2(70)
P=140
So 140 feet of fencing is needed to replace the fence.
The amount of sod needed is equal to the area which is LW
A=30(40)=1200 ft^2
