Linear Inequality with One Variable

When solving linear inequalities with one variable, we need to find the values of the variable that satisfy the given inequality. In this case, we have a rectangle with one side shorter than the other by 5.2 cm, and we need to find the possible length of the longer side if the perimeter is less than 52 cm.

Given Information

- Let's denote the length of the shorter side as x and the length of the longer side as y. - We know that y = x + 5.2. - The perimeter of a rectangle is given by the formula: P = 2(x + y).

Solution

To find the possible length of the longer side, we can use the given information to form an inequality for the perimeter and solve for y.

The perimeter is less than 52 cm, so we have: 2(x + y) < 52.

Substitute y = x + 5.2 into the inequality: 2(x + x + 5.2) < 52.

Simplify the inequality: 2(2x + 5.2) < 52.

Now, solve for x: 4x + 10.4 < 52.

Subtract 10.4 from both sides: 4x < 41.6.

Divide by 4: x < 10.4.

So, the possible length of the shorter side is less than 10.4 cm.

Conclusion

The length of the longer side can be any value greater than x + 5.2, where x < 10.4. Therefore, the length of the longer side can be any value greater than 15.6 cm if the perimeter is less than 52 cm.
