Algebra-1

Let's assume the width of the rectangle is "W" cm.

According to the given information, the length of the rectangle is 4 cm longer than the width, so the length is "W + 4" cm.

The perimeter of a rectangle is given by the formula: 2(length + width).

We know that the perimeter is 80 cm, so we can set up the following equation:

2(W + (W + 4)) = 80   ---(1)

Simplifying...
