x×3x=7500
3x*2=7500
X*2=2500
X=50
3x = 150
2(50+150)(10)=4000
3x*2=7500
X*2=2500
X=50
3x = 150
2(50+150)(10)=4000

hey mate here is your answer
let
length=3x
breadth=x
area of the rectangle=l×b
7500=3x×x
7500=3x^2
x^2=7500/3
=2500
x=√2500=50
so length=3x=3×50
=150
breadth=50
perimeter=2(150+50)
2×200
400
cost of fencing per metre=10Rs
cost of fencing for 400m=400×10
4000m
