Question

the length of the rectangle is 3 times its width if the perimeter is 84 M find the length of the rectangle

Answer 1

Hlo friend.. Cutiepie Here..

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

HOPE IT HELPS YOU...

Answer 2

Let the width of rectangle be x.

Therefore, it's length will be 3x.

A.T.Q.

Perimeter of rectangle = 84m

→ 2(3x+x) = 84

→ 8x = 84

→ x = 84/8

→ x = 10.5 m

Width = 10.5 m
Length = 10.5×3 = 31.5m
