Question

A bar of chocolate is placed next to a measuring scale. The ends of the bar are at 5.6 cm and 20.2 cm markings on the scale. What is the length of the chocolate bar?

• A. $5.6\text{cm}$
• B. $20.2\text{cm}$
• C. $25.8\text{cm}$
• D. $14.6\text{cm}$

Answer 1

The correct option is D $14.6\text{cm}$

The length of the chocolate bar can be calculated as the difference in the readings marked on the scale. Hence, the length is: $\Rightarrow 20.2-5.6=14.6\text{cm}$
