Answer 1

40 см = 0,4 м
60 см = 0,6 м
0,4 * 0,6 = 0,24 м² - площадь боковой стенки

Answer 2

Calculating the Area of the Side Wall

To find the area of the side wall of the shelf, we can use the formula for calculating the area of a rectangle, which is Area = Length x Width.

Given that the depth of the shelf is 40 cm and the height is 60 cm, we can use these measurements to calculate the area of the side wall.

Calculation

Using the formula Area = Length x Width, where the length is the height of the shelf (60 cm) and the width is the depth of the shelf (40 cm), we can calculate the area of the side wall:

Area = 60 cm x 40 cm = 2400 cm²

Therefore, the area of the side wall of the shelf is 2400 square centimeters.

This calculation is based on the dimensions provided for the shelf and the formula for calculating the area of a rectangle.
