The rectangle is 8 cm long and 3 cm wide. This rectangle is divided into two parts so that the area of each of them is 3 times larger than the other. Find the area of each part of the rectangle.

First, find out how much the total area of a given rectangle becomes, multiply the length by the width:

1) 8 cm * 3 cm = 24 cm2.

We need to divide the found area into three parts – then we can find out the area of the smaller part of this figure:

2) 24 cm2 / 3 parts = 6 cm2.

If we know that the second part of the rectangle is three times larger than the first, then we subtract the area of 2 parts, increasing the area of 1 three times, that is, multiplying by three:

3) 6 cm2 * 3 times = 18 cm2.

Result: the area of 1 part is 6 cm2, and the area of 2 is 18 cm2.
