Question

the measure of two adjacent sides of a rectangle is in the ratio 11:10.If the perimeter of the rectangle is 84cm,then find its length and breadth.​

Answer 1

Answer:

l=22cm and b=20cm

Step-by-step explanation:

let length be 11x and breadth be 10x

then,

2(l+b)=P

2(11x+10x)=84cm

21x=42

x=2cm

length=11x=11×2=22cm

breadth=10x=10×2=20

Answer 2

length-22cm and breadth- 20cm

Step-by-step explanation:

suppose

length and bread-x

length-11x and bredth=10x

2(11x*10x)84

42=11x+10x

so. x=42./21

therefore x=2

length=11*2=22cm

and breadth-=10*2=20cm
