The perimeter of the rectangle = 98cm. Its length is 28cm more than the width. Find the width of the rectangle.

1. Suppose that the width of the given rectangle is x cm.

2. Since we know that its length is 28 cm longer than its width, therefore it will have a length of (x + 28) cm.

3. Let’s make an equation and find out what the width of a given rectangle is, if we are given that its perimeter is 98 cm.

x + x + x + 28 + x + 28 = 98;

4x = 98 – 28 – 28;

4x = 42;

x = 42/4;

x = 10.5 cm.

Answer: The width of the given rectangle is 10.5 cm.
