Question

The perimeter of the rectangle below is 130 units. Find the length of side PS.Write your answer without variables.

Answer 1

we have the following:

`\begin{gathered} P=2\cdot w+2\cdot l \\ 130=2\cdot(4y)+2\cdot(5y+2) \\ 130=8y+10y+4 \\ 18y=126 \\ y=(126)/(18) \\ y=7 \end{gathered}`

therefore,

`PS=5y+2=5\cdot7+2=37`

The answer is 37
