the length of a rectangle is equal to triple the width. if the perimeter is 8 centimeters. what is the length and the width of the rectangle

Length = 3 cm

Width = 1 cm

Step-by-step explanation:

Let the length of rectangle be l and width of rectangle be w.

According to problem,

l = 3w {Length of rectangle is equal to triple the width}

And Perimeter, P = 8 cm

Since, P = 2 (l + w)

or 8 = 2 (l + w)

Plug l = 3w in the above perimeter equation.

We get:

8 = 2 (3w + w)

8 = 2 (4w)

8 = 8w

or w = 1 cm

Then length, l = 3w = 3 * 1 = 3 cm

Hence length of rectangle is 3cm and width of rectangle is 1cm.
