Question

plzzzz help me with this prblm

Answer 1

let the length and breadth are 6x and 5x respectively
then area= l×b=27000m^2
6x × 5x=27000m^2
30x^2=27000
x^2=27000/30
x^2=900
x=√900=30m
so length=6×30=180m
breadth=5×30=150m
perimeter=2(180+150)=2(230)=460m
cost for meter = ₹15
for 460m cost=460×15=₹6900

Answer 2

Let the Length and breath be 6x and 5x respectively.
Then area = L*b= 27000m^ 2
6x x 5= 27000^2
30x^2=27000.
