The length of the rectangle is 7 whole 1/2 cm, and its area is 15 cm2. what is the width of the rectangle?

The width of the rectangle (a) -? cm;

The length of the rectangle (b) is 7 1/2 cm;

Area (Sp.) – 15 cm ^ 2.

You can immediately convert the numerical value of the length of the rectangle from a mixed fraction to an ordinary one, i.e. 7 1/2 = 15/2.

The area of a rectangle is the product of its length and width.

Sp. = a * b.

Knowing from the condition the value of the area itself, as well as the length of the rectangle, we can calculate its width:

a = Spr. : b = 15: 15/2 = 15 * 2/15 = 2 (cm).

Answer: The width of the rectangle is 2 cm.
