Question

3. Solve the application problem. Find the perimeter of a ruler that measures 6 inches by inch. 5 inches 2 13 in 5 in2 13 in.

Answer 1

Option (D)

Given:

The measure of the ruler is 6 inches by 5/6 inch.

The objective is to find the perimeter of the ruler.

The formula to find the perimeter is sum of all the sides.

So, the perimeter of the ruler can be calculated as,

`\begin{gathered} P=6+(5)/(6)+6+(5)/(6) \\ P=6+6+(5)/(6)+(5)/(6) \\ P=12+(10)/(6) \\ P=(12(6)+10)/(6) \\ P=(72+10)/(6) \\ P=(82)/(6) \\ P=13(4)/(6) \\ P=13(2)/(3)\text{ in} \end{gathered}`

Hence, option (d) is the correct answer.
