The area of a rectangle is equal to the product of its sides S = a * b.
Let’s solve this task by action.
1. Let’s express the sizes of the sides, if necessary, in centimeters.
20 mm = 2 cm.
2. Using the formula for calculating the area, we find it.
S = a * b = 11 * 2 = 22 cm2.
Answer: The area of a rectangle with sides of 11 cm and 20 mm is 22 cm2.
