Question

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

Answer 1

Length is twice the Width

 

Perimeter = 126 ft.

 

let width = W

 

length = 2W

 

P = 2 length + 2 width

 

126 ft. = 2(2W) + 2W

 

126 ft. = 6W

 

  21 ft. = W

 

width is 21ft., length is 42 ft.
