Question

Perimeter of a rectangle is 96 m. Its length is 3
times its width. Find its length and breadth.​

Answer 1

Answer:

Length=36m, Breadth=12m

Step-by-step explanation:

Let it's length and breadth be 3x and x respectively,

ATQ,

2(3x+x)=96

=> 8x=96

=> x=12

So, the length and breadth are 3(12)=36 and 12 respectively

Answer 2

Answer:

length = 36m

breath = 12m

Step-by-step explanation:

let the length be 2x

and width be x

2(l+b) =P

2 ( 3x + x ) = 96 m

6x + 2x = 96m

8x = 96m

x = 96m/8

x = 12m

width = 12m

length = 3x = 3×12m

= 36m

check= 2 ( 36m + 12m )

= 72m + 24m

= 96

hope this help you
