Question

the length of a rectangler field is it s peremeter is 400 meters. find its length and brreadth.

Answer 1

hey here is your answer

let the length be x
so,breadth will be 3x

Now According to formula
2 (l+b)=400
2 (x+3x)=400
2×4x=400
4x=400/2
4x=200
x=200/4
x=50

so, length =x=50
and breadth =3x=3×50=150
