the length of a rectangle is equal to triple the width.
find the width of the rectangle if the perimeter is 80 centimeters.

10 cm

Step-by-step explanation:

Let Length be denoted by L and Width be denoted by W

given Length is triple the width , or L = 3W

By definition:

Perimeter of rectangle,

= Length + Length + Width + Width

= 2L + 2W   (substitute L = 3W)

= 2 (3W) + 2W

= 6W + 2W

= 8W

Given perimenter is 80 cm,

8W = 80 cm

W = 80 / 8 = 10 cm

10 cm

Step-by-step explanation:

If the length of a rectangle is equal to triple the width, the width of the rectangle is 10 cm if the perimeter is 80 centimeters.

L = 3w

P = 80

Formula: a = l × w

8W = 80 cm

W = 80 / 8 = 10 cm

Therefore, the width of the rectangle is 10 centimeters.
