Question

The length of a rectangle is three times its width. If the perimeter of the rectangle is 96 metres, find the length and breadth of the rectangle.

Answer 1

Answer:

The length of the rectangle is 36 m and breadth is 12 m.

Step-by-step explanation:

Given :

The length of a rectangle is three times its width.

The perimeter of the rectangle is 96 m.

To find :

the length and breadth of the rectangle.

Solution :

Let the length of the rectangle be l m and breadth be b.

length = 3(width)

l = 3b

Perimeter of the rectangle = 2(length + breadth)

96 = 2(l + b)

96/2 = 3b + b

48 = 4b

b = 48/4

b = 12

Therefore, the breadth of the rectangle is 12 m.

Length :

Length = 3(12)

Length = 36 m
