Question

If braeth of a room is one fourth of its length and the perimeter of the room is 20m. Find length and breadth of room.

Answer 1

Answer:

length =x

breadth =1x/4

perimeter of rectangle =2(l+b)=20m

2(l+b)=20

2(x+ x/4)=20

4x+x/4 =20/2

5x/4=10

x=10×4/5

x=8

therefore, length is 8m and breadth is 2m
