The length of the rectangle is 4 times its width. Find the area of a rectangle if its width is 12 meters less than its length.

Let’s solve this problem using the equation.

Let the width of the rectangle be x meters, then the length of the rectangle is 4 * x meters. We know that the width is 12 meters less than the length. Let’s make the equation:

4 * x – x = 12;

x * (4 – 1) = 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 meters – the width of the rectangle;

4 * 4 = 16 meters – the length of the rectangle;

4 * 16 = 64 m ^ 2 – the area of the rectangle.

Answer: 64 m ^ 2.

Answer: 64 m ^ 2.
