The width of a rectangle is an eighth of its length. Calculate the area of this rectangle if its length is 32cm.

First of all, let’s calculate what the width is. To do this, we must find 1/8 of 32 centimeters. To find the part of a number, this number is multiplied by the part.

1/8 * 32 = 32/8 = 4 cm.

The next step is to calculate what is the area of a rectangle 32 cm long and 4 cm wide.

S = 4 * 32 = 128 cm².

Answer: 128 cm².
