Question

18. The length of a hall is 15 metres. It is represented by a line 3 centimetres long on a scale drawing. What scale is used? (a) 1cm represents 1 metre (b) 1cm represents 2 metres (c) 1cm represents 3 metres (d) 1cm represents 5 metres (e) 1cm represents 15 metres​

Answer 1

Simplify the problem first.

A 15 m line is represented as 3 cm long.

15 m = 3 cm

15/3 m = 3/3 cm

5 m = 1 cm

1 cm represents 5 metres. (d)

Hope this helps.
