Question

The length of a rectangle is 3. Times it's width its perimeter is 96 what is length

Answer 1

Answer:

length =36 and breadth =12

Step-by-step explanation:

Let we assume length of the rectangle is 3 x and width of the rectangle is x.

Given,perimeter of the rectangle=96

2(l+w)=96

2(3 x + x)=96

2(4 x)=96

8 x=96

x=12

∴Length of the rectangle=3 x

                                         =3(12)

                                         =36

∴Breadth of the rectangle=12
