One side of the rectangle is 2 times longer than the other, the total length of these two sides is 12 centimeters, find the length of each side of this rectangle.
Let’s solve this problem using the equation.
Let the length of the first side of the rectangle be x centimeters, then the length of the second side of the rectangle is 2 * x centimeters. We know that the total length of these two sides of the rectangle is 12 centimeters. Let’s make the equation:
x + 2 * x = 12;
x * (1 + 2) = 12;
x * 3 = 12 (in order to find an unknown factor, you need to divide the product by a known factor);
x = 12: 3;
x = 4 centimeters – the length of the first side of the rectangle;
4 * 2 = 8 centimeters – the length of the second side of the rectangle.
Answer: 4 centimeters; 4 centimeters; 8 centimeters; 8 centimeters.
