As given by the question

There are given that the side length is (2x+3) and perimeter is 60 cm.

Now,

From the formula of perimeter:

[tex]\text{Perimeter =4}\times side[/tex]

So,

[tex]\begin{gathered} \text{Perimeter =4}\times side \\ 60=4\times(2x+3) \\ 60=8x+12 \\ 8x=60-12 \\ 8x=48 \\ x=\frac{48}{8} \\ x=6 \end{gathered}[/tex]

Then,

Put the value of x into the given side length (2x+3)

So,

[tex]\begin{gathered} 2x+3=2\times6+3 \\ =12+3 \\ =15 \end{gathered}[/tex]

Hence, the one side of length is 15 cm.
