Let's denote the width of the rectangle as w.
Since the perimeter of a rectangle is given by the formula P = 2L + 2W, where L is the length and W is the width, we can set up the following equation:
50 = 2(18) + 2w
Simplifying the equation, we get:
50 = 36 + 2w
Subtracting 36 from both sides of the equation, we get:
14 = 2w
Dividing both sides of the equation by 2, we get:
7 = w
Therefore, the width of the rectangle is 7 cm.
The formula for the area of a rectangle is A = L * W, where A is the area, L is the length, and W is the width. Substituting the given values, we get:
A = 18 * 7
Calculating the area, we get:
A = 126
Therefore, the area of the rectangle is 126 square cm.
