The area of the rectangle is 56 cm2 and its length is 70 mm. Find the width.

It is known from the condition that the area of the rectangle is 56 cm2, and its length is 70 mm. In order to find the width of the rectangle, recall and apply the formula for finding the area of a rectangle.

The area of a rectangle can be calculated using the formula:

S = a * b, where a and b are the length and width of the rectangle.

Let us express the width in turn, the area and the length.

b = S / a;

But first of all, let’s translate 70 mm into cm and get 7 cm.

Substitute and calculate:

b = 56/7 = 8 cm rectangle width.

Answer: 8 cm width of the rectangle.
