Question

7. The length of a rectangular hallway is 3 times its breadth. If the perimeter of the hallway is

48 m, find its length and breadth.​

Answer 1

Answer:

Therefore,.

The perimeter of rectangle = 2(l+b)

So,

2(48+3) = 51.

2×51 = 102

so,

Answer is 102.

Answer 2

Answer:

breadth=x

length= 3x

perimeter=2(l+b)

48= 2(3x+x)

48= 2×4x

48= 8x

x=6

breadth=6

length= 6×3=18
