Question

A pentagon has three sides with length x, and two sides with the length 3x. If x is $\frac{2}{3}$ of an inch, what is the perimeter of the pentagon ?

• A. $6$ inches
• B. $7$ inches
• C. $9$ inches
• D. $12$ inches

Answer 1

The correct option is A $6$ inches

6 inches: The perimeter of a pentagon is the sum of its five sides: $x+x+x+3x+3x=9x$. If $x$ is $\frac{2}{3}$ of an inch, the perimeter is $9\left(\frac{2}{3}\right)$ , or 6 inches.(option A)
