Find the area of a rectangle if it is 6 centimeters wide and 3 times longer.

1. First of all, it is necessary to determine the length of the rectangle, if it is known from the condition that it is three times its width, we obtain the following expression for determining the length:
6 cm * 3 = 18 cm.
2. Now we can determine the area of a rectangle by the following formula S = a * b, where S is the area of a rectangle with length a and width b, then we get the following solution:
Area = 18 cm * 6 cm = 108 cm2.
Answer: As a result, we got the value of the area of the figure equal to 108 cm2.
