Question

perimeter of the rectangle is 96m it's length is 3 times it's width find length and breadth​

Answer 1

Answer:

Step-by-step explanation:

perimeter=96m

let the length be 3x

width will be x

as per condition

2(3x+x)=96

8x=96

x=96/8

x=12

width will be 12

length will be 3x=12*3=36

Answer 2

Answer:

Lenght - 36m, Bredth - 12m.

Step-by-step explanation:

formula for perimeter of a rectangle = 2(l+b).

Given that length is 3 times the breadth

=> l = 3b.

perimeter is 96.

So,

2 (l+b) = 96

=> 2 (3b+b) = 96

=> 4b = 96/2

=> 4b = 48

=> b = 12.

l = 3b => 3 x 12 => 36.

Length of the rectangle is 36m and breadth is 12m.
