The length of rectangle is twice its width. the perimeter of the rectangle is 126 feet

length = 42 feet , width = 21 feet .

Step-by-step explanation:

Given  : The length of rectangle is twice its width. The perimeter of the rectangle is 126 feet.

To find : Find the width , length.

Solution : We have given  

Length = 2 * Width .

Perimeter = 126 feet  .

Let length = l

Width = w .

Perimeter = 2 ( length +  width )

Plug the values

126  = 2 ( 2 w + w )

126 = 2 ( 3w).

126 = 6w .

On dividing both sides by the number 6

w = 21 feet .

Width = 21 feet .

Length = 2 * 21= 42 feet .

Therefore, length = 42 feet , width = 21 feet .
