Question

There is a narrow rectangular plot, reserved for a school, in Mahuli village. The
length and breadth of the plot are in the ratio 11:4.At the rate Rs100 per metre it will
cost the village panchayat Rs 75000 to fence the plot. What are the dimensions of
the plot?

Answer 1

hey mate here is ur answer :-

let the length be 11x and breadth be 4x.

perimeter=2(11x+4x)=30x

cost=30x ×100=3000x

3000x=75000

x=25

so

length =11×25=275m

breadth = 4×25=100m

hope it helps ❤

Answer 2

Answer:

Step-by-step explanation:

Cost - 75000

Perimeter   =  75000/100

                   =750

Legnth + breadth = 750/2

=375

Ratio : 11: 4          +  15

So 375/15 = 25

Thus dimensions are : 275cm 100cm
