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

Answer:
1107 feets below sea level
Step-by-step explanation:
Given that :
Initial elevation of submarine = 984.6 feets below sea level
Depth of dive from initial elevation = 122.4 feets below sea level
The elevation after the dive :
Initial elevation + depth of dive
984.6 + 122.4
= 1107 feets below sea level
Answer:
Step-by-step explanation:
x=4
y=(x+4) +8 because x is equal TO 4 so it equals 8.
Then do y+x times 4
