Question

The length of a rectangular hallway is 3 times it's breadth.If the perimeter of the hallway is 48m,find its length and breadth.

Answer 1

length is 18cm and breadth is 6cm

Answer 2

Let the breadth be x
Hence the length is 3x

But perimeter of rectangle = 2(l+b)
So,48m = 2(x+3x)
48m= 2(4x)
48m = 8x
48/8=x
6=x

therefore breadth is 6m and length is 18 m
