Question

the perimeter of a rectangular plot is 200 m the length of the plot is 10 meter more than twice its breadth find the length and the breadth of the plot

Answer 1

let the breadth of the plot be x
therefore its length=2x+10
perimeter of plot=2(l+b)=200
2(2x+10+x)=200
3x+10=100
3x=90. x=30
therefore breadth of plot =30m
length of plot =2×30+10=70m

Answer 2

Soln:-
let the breadth be x m
therefore length = 2x+10 m
A/q,
2(2x+10+x)=200m
2(3x+10)=200m
6x+20=200
6x=200-29
6x=180
x=180/6
=30
Breadth =30m
length =2×30+10
=70m
