Question

1. a scale drawing of a garden is made with a scale of 1:200. if a drawn flower bed is 2 cm long, how long is it in real life?

a. 40 cm
b. 100 cm
c. 200 cm
d. 400 cm

Explanation:

Step1: Understand the scale ratio

The scale is \(1:200\), which means \(1\) unit on the drawing represents \(200\) units in real life.

Step2: Calculate the real - life length

If the drawing length \(l_{drawing}=2\) cm, and using the formula \(l_{real}=l_{drawing}\times200\).
Substitute \(l_{drawing} = 2\) into the formula: \(l_{real}=2\times200\).

Answer:

\(400\) cm, so the answer is d.
