Question

The length of a rectangle is three times its width . It the perimeter of the rectangle is 96 meter , Find the length and breadth of the rectangle​

Answer 1

Answer:

Let length be 'L' mtrs

and breadth be 'b' mtrs

NOW,

ACCORDING TO THE QUESTION

3L=b------(1)

Now,

P(rect.)=2(L+b)

96=2(L+3L)

96=2(4L)

96=8L

On solving v get

L=12m

Now putting value of L as 2 in ---(1)

3L=b

3(12)=b

36=b

b=36m

Length is 12m

Breadth is 36m

Answer 2

Answer:

This is step by step answer in which first you have to assume the values and then using the perimeter's formula You have to find the assumed ones
