(a) The scale of a map is 1 cm represents 25 m.
(i) The length of a path is 240 m.
Work out the length, in centimetres, of the path on the map. [1]
(ii) The scale 1 cm represents 25 m can be written in the form 1 : \(k\).
Find the value of \(k\). [1]
(b) The scale drawing represents a park.
Scale: 1 cm represents 25 m
A new play area must be
- no more than 150 m from B
- closer to AD than to CD.
Construct and shade the region where the play area can be positioned.
Show all your construction lines. [5]
