Find the width of a rectangular tile if its area is 40 cm and the length is 8 cm.

In order to determine the width of the tile, you need to use the following formula:

b = S / a,

Where:

b is the width of the tile;

S is the area of the tile (according to the problem statement 40 cm ^ 2);

a – the length of the tile (according to the problem, 8 cm).

Substitute the values from the condition into the formula and get:

b = 40/8 = 5 cm.

Answer: The width of the tile is 5 cm.
