Question

The lenght of a rectangle is 3 times its breadth if the perimeter os 48 m find the length and breadth of the rectangle

Answer 1

Answer:

length = 18m ; breadth = 6m

Step-by-step explanation:

Let the breadth be x and the length be 3x

Therefore,

Perimeter of the rectangle = 2 (length + breadth)

⇒ 48 = 2 (x + 3x)

⇒ 48 = 2 (4x)

⇒ 48 = 2 × 4x

⇒ 48 = 8x

⇒ 48 ÷ 8 = x

⇒ 6 = x

Therefore,

length = 3x = 3×6 = 18m

breadth = x = 6m
