Question

The length of a room is three times its breadth. If the perimeter of the room is

64m, find the length and breadth of the room.

Answer 1

Answer:

breadth = 8m length = 24m

Step-by-step explanation:

let length be l and breadth be b

l = 3b

2[l+b] = 64

2[3b+b] = 64

8b = 64

b = 8

l = 3b

l = 24m

mark me as brainliest

Answer 2

let the breadth of the room be x

then the length of the room = 3x

Perimeter=2*(l+b)

64=2*(3x+x)

64=6x+2x

64=8x

x=8

Length= 3x=3×8m =24m

Breadth=x= 8m
