Question

The length and breadth of a rectangle are in the ratio 4 : 3. If its perimeter is 154 cm, find its

length and breadth.​

Answer 1

Answer:

Ratio of l and b =4:3

perimeter =2(l+b)

so,

length =44cm

and

breadth =33

Answer 2

Answer:

Given

let the req no be=x

so here are= 4x and 3x

perimeter=154cm

so,

by formula

perimeter of rectangle= 2(l+b)

put up the value

154=2(4x + 3x)

take the digit 2 to the another side

so,

154/2= 4x +3x

77=7x

therefore,

77/7=x

11 =x

so,

here we found the x but the question is not over yet

now,

4x = 4× 11= 44

3x =3×11= 33

so the length and breadth are

44cm and 33 cm = Ans.
