Question

The length and breath of therectangle. Are in ratio 5:2 leave the perimeter is 350 find it's area

Answer 1

let the common multiple be x
therefore l=5x and b=2x

2(l+b)=350.......given

2(5x+2x)=350

10x+4x=350

14x=350

x=350/14

x=50/2

x=25

hence, area=2x×5x

=50×125

=6250unit²

Answer 2

Hope it'll help.....
