To complete this task, we must calculate what the length of the rectangle is. To do this, we must find how many centimeters are 5/21 of 42 centimeters. To do this, we multiply the part by the number.
5/21 * 42 = 5 * 42/21 = 210/21 = 10 cm.
Knowing that the width is 42 cm, and the length is 10 cm, we calculate what the area of the given rectangle is equal to.
S = 42 * 10 = 420 cm².
Answer: 420 cm².
