Question

In the scale drawing below, each side is.38 cm long. Use the scale factor shown. What is the perimeter of the actual object? I cm - 6.5 m O A. 12.35 m O B. 52.25 m C. 42 m D. 61.75 m

Answer 1

Answer: 12.35 m

Explanation:

Answer 2

The scaled perimeter of the polygon is,

`\begin{gathered} P=5*0.38 \\ P=1.9\text{ cm} \end{gathered}`

The expression to calculate the actual perimeater is,

`\text{Actual Perimeter=P}* Scale\text{ factor.}`

Here, scale factor is 6.5 cm.

`\begin{gathered} \text{Actual Perimeter=1.9}*6.5 \\ =12.35\text{ cm} \end{gathered}`

Thus, the actual perimeter of the polygon is 12.35 cm.
