Answer:
A) 20
Step-by-step explanation:
Let
x-------> <span>the length of the pond
</span>y-------> the width of the pond
we know that
[volume of the pond]=area of the base*deep
area of the base=volume/deep
volume=72000 in³
deep=24 in
area of the base=72000/24------> 3000 in²
area of the base=x*y
3000=x*y-------> equation 1
x=2y-----> equation 2
substitute equation 2 in equation 1
3000=[2y]*y------> 2y²=3000-----> y²=1500------> y=38.7 in
x=2y----> x=2*38.7----> x=77.4 in
the answer is
the length of the pond is 77.4 in
the width of the pond is 38.7 in
