The width of the rectangle is 48 cm, which is 3.16 of its perimeter. Find the length of the rectangle.

To solve this problem, you first need to determine the perimeter of the rectangle.

Since we know that the width is 3/16 of the mouth of the perimeter, to determine it we divide the width by the known part.

We get:

48 / 3/16 = 48 * 16/3 = 16 * 16 = 256 cm.

The perimeter is twice the sum of the sides of the rectangle.

In this case, the sum of the length and width of the figure will be:

256/2 = 128 cm.

Find the length of the rectangle.

To do this, subtract the width value from the resulting sum of the sides.

128 – 48 = 80 cm.

Answer: The length of the rectangle is 80 cm.
