1.	the length of a rectangle is three times its breadth the perimeter is 84 metre find the length of the rectangle
Answer» Answer: Here is ur answer : Let width be X. Length be 3x. Perimeter = 84 m Perimeter of Rectangle = 2( l + B) ➡️ 84 = 2 (3x + x) ➡️ 84/2 = 4x ➡️ 42 = 4x ➡️ x = 42/4 ➡️ x = 10.5 Width = 10.5m Let width = 31.5m

the length of a rectangle is three times its breadth the perimeter is 84 metre find the length of the rectangle

Answer:

Here is ur answer :

Let width be X.

Length be 3x.

Perimeter = 84 m

Perimeter of Rectangle = 2( l + B)

➡️ 84 = 2 (3x + x)

➡️ 84/2 = 4x

➡️ 42 = 4x

➡️ x = 42/4

➡️ x = 10.5

Width = 10.5m

Let width = 31.5m
