Question

if the length and breadth of rectangle are in the ratio 2:3 and it's perimeter is 50 cm then find its length and breadth​

Answer 1

let the length and breadth be 2x and 3x.

perimeter = 2( l+b )

50 = 2(2x+3x)

25 =5x

x= 5

hence the length and breadth are 10cm and 15cm

Answer 2

hi dear,

Good Morning..

Here is ur answer :-

Given :-

Perimeter :- 50 cm

ratio of length and breadth :- 2:3

Answer:-

let the length and breadth be :- 2x & 3x

=> Perimeter of Rectangle :- 2( l+b )

:. Perimeter = 2( 2x+3x )

50 = 2( 5x )

50 = 10x

x = 50/10

:. x = 5

length = 2x = 2(5) = 10 cm

breadth = 3x = 3(5) = 15 cm

hope it helps......
