Question

the length and breadth of a room are in the ratio 3:2.if it's perimeter is 60m.find the dimension of the room.​

Answer 1

Answer:

Length and breadth of the room are in ratio = 3:2

let their measured be = length = 3x

breadth = 2x

perimeter of room = 60m

2(l+b)

= 2(3x+2x) =60

= 2(5x) = 60

5x = 60/2

x = 30/5

x = 6

length = 3x

= 3×6 = 18

breadth = 2x

= 2×6 = 12
