Question

A scale drawing of a lake has a scale of 1 cm to 80 m. If the actual width of the lake is 1,000 m, what is the width of the lake on the scale drawing? Answers with fractions must be entered at a decimal. For example 1 1/2 would be 1.5 and 1 1/4 would be 1.25.

Answer 1

Answer: 12.5cm

Explanation:

From the question, we are informed that a scale drawing of a lake has a scale of 1 cm to 80 m. This can be represented as a fraction of 1/80.

Since the actual width of the lake is 1,000 m, the width of the lake on the scale drawing will be:

= 1/80 × 1000

= 12.5cm

The width of the lake on the scale drawing is 12.5cm.
