Question

Find the values for x so that the perimeter of this rectangle is no greater than 70 centimeters

Answer 1

The perimeter of the given rectangle is:

Since the perimeter must be equal to or smaller than 70 cm we can set the following inequality:

`2x+60\leq70.`

Solving the above inequality for x, we get:

`\begin{gathered} 2x\le70-60, \\ 2x\le10, \\ x\le(10)/(2), \\ x\le5. \end{gathered}`

Answer: Recall that x must be greater than zero since it is the length of the side of the rectangle, then
