Question

The perimeter of thefigure shown on theright is 42.5 units.What is the lengthof side S in units?

Answer 1

The perimeter of any figure refers to the sum of all its sides.

So for us to find the perimeter of the figure, we will sum(add) up all its sides

`3.75\text{ + 12.5 + 2.5 + S + 12.5 = 42.5}`
`collect\text{ like terms }`
`\begin{gathered} 31.25\text{ + S = 42.5} \\ S\text{ = 42.5 -31.25} \\ S\text{ = 11.25} \end{gathered}`

The correct option is G
