The width of a rectangle is one fourth of its length. Calculate the area of this rectangle if its length is 8cm.

The first step is to calculate what the width of the rectangle is, knowing that it is 1/4 of the length, that is, from 8 cm. To find the part of the number, you need to multiply this number by the part.
8 * 1/4 = 8/4 = 2 cm.
Let’s calculate what the area of the rectangle is. To do this, we must multiply the length by the width.
S = 2 * 8 = 16 cm².
Answer: 16 cm².
