Find the area of a rectangle if its length is 12 cm and its width is equal to the side of an equilateral

Find the area of a rectangle if its length is 12 cm and its width is equal to the side of an equilateral triangle with a perimeter of 48 cm.

Let us determine what the width of the specified rectangle will equal if from the condition of our problem we know for sure that it corresponds to the length of the side of an equilateral triangle, whose perimeter is 48 centimeters:

48: 3 = 16.

Let’s determine what the area of the specified rectangle will be, because from the school mathematics course we know that it is calculated through the product of its dimensions:

12 * 16 = 192.

Answer: With such initial data, the area of the specified rectangle will be 192 cm2.
