12 Question solve kigiye

Answer 1

let the length be 11 x and breadth be 4 x.
therefore perimeter = 2(l+b)
=2(11x+4x)
=2×15x=30x
cost of fencing the plot at the rate rs 100 per metre=30x×100
75000=30x×100
75000/100=30x
750/30=x
x=25

now , length =11x=11×25=275m
and breadth =4x=4×25=100m

I hope it helps u

Answer 2

Perimeter= Total cost/ Rate
= 75000÷100 = 750 mts.
Let the length and breadth be 11x and 4x respectively
A.T.Q.
Perimeter= 2 ( L+B)
or,750=2(11x+4x)
or,750=30x
or,x= 750/30. =25
Length= 11×25=275 mts.
Breadth=4×25=100 mts.
