The perimeter of a rectangle is 24 meters and it's length is 3 times the width. What is the length and width of the rectangle

Length is 9meters and width is 3 meters

steps:

let's assume width of a rectangle = a meters

than length of the rectangle = 3*a = 3a

perimeter = 24 meters

formula to find perimeter: p = 2 (l+w)

substitute the values of in the formula

24 = 2 (3a+a)

24 = 2 (4a)

24 = 8a

24/8 = a

3 = a

a is width of the rectangle = 3 meters

length of the rectangle = 3 * a = 3*3 = 9 meters

hence and is length 9 meters and width 3 meters
