the length of a rectangle is twice 5he breadth if the perimeter of the rectangle is 120m . find the breadth​ ki u​

Answer»

Answer:

Given :

The LENGTH of Rectangle is twice the breadth.

Perimeter of Rectangle = 120 m

To find :

Breadth of rectangle?

Solution :

LET breadth of rectangle be x m

Then, Length of rectangle is 2x m

According to the Question:

Perimeter of Rectangle = 120 m

We know that,

Perimeter of Rectangle = 2(l + B)

→ 2(x + 2x) = 120

→ x + 2x = 120/2

→ 3x = 60

→ x = 60/3

→ x = 20

Therefore,

Breadth of Rectangle, x = 20 m

Length of Rectangle, 2x = 20 × 2 = 40 m

Hence, Length and Breadth of rectangle is 40 m and 20 m respectively.
