Question

find the perimeter of a rectangular field those length is 4 times its width and which has which has area equal to 20,736sq.m

​

Answer 1

Answer:

Step-by-step explanation:let width be 'x'

Therefore,lenght =4x

Area=20736m²

l×b=20736

4x×x=20736

4x²=20736

x²=5184

x=72

Therefore,width=72m and lenght=4×72=288m

Now, perimeter=2(l+b)=2(72+288)=2×360=1440m
