Given:

A rectangle has a length 5 meters more than five times the  width.

The area of the rectangle is less than 100 meters  squared.

To find:

The expression or inequality that represents all possible  widths of the rectangle.

Solution:

Let x be the width of the rectangle.

Length of the rectangle is 5 meters more than five times the  width.

Area of rectangle is

The area of the rectangle is less than 100 meters  squared.

Divide both sides by 5.

It is true if one factor is negative and other is positive. So,

    ...(i)

      ...(ii)

Using (i) and (ii), we get

Therefore, the required expression or inequality for possible

widths of the rectangle is .
