Hypotenuse^2=12^2+5^2=144+25=169
⇒ hypotenuse =V169=13 cm
Volume = π • r² • height
Height = Volume / (PI * radius^2)

Answer:
Let the width of the garden =x meter
Then length=(x+4) meter
Half perimeter =36 m
So perimeter of garden =(2×36)=72 meters
According to the question
⇒2(l+b)=72
⇒2(x+x+4)=72
⇒2x+2x+4=74⇒4x=64⇒x=16 meters
Hence,the width of the garden =16 meters
The length of the garden =(16+4)=20 meters
