The perimeter is 16 cm. The length of the rectangle is 2 cm longer than the width. Find the sides of the rectangle

1. Let the width of the rectangle be y, then its length is 2 + y. Using the formula for the perimeter of a rectangle P = 2a + 2b, where P is the perimeter of a rectangle with length b, width a, we will compose the equation:
2y + 2 * (2 + y) = 16,
2y + 4 + 2y = 16,
4y = 16 – 4,
4y = 12,
y = 12/4,
y = 3.
2. Find the length of the rectangle:
3 + 2 = 5 cm.
Answer: the sides of the rectangle are 3 cm and 5 cm.
