Solution:
To calculate the area of the top of a table with sides 1.2 m and 0.9 m, you'll use the formula for the area of a rectangle, which is:Area = length × widthGiven the sides are in meters, and you need the answer in square centimeters (cm²), you'll need to convert the measurements from meters to centimeters before calculating. There are 100 centimeters in a meter, so:Length: 1.2 m = 120 cmWidth: 0.9 m = 90 cmNow, calculate the area:Area = 120 cm × 90 cmArea = 10800 cm²Therefore, the area of the top of the table is 10,800 cm².
