A triangular field ARC is such that AB = 90 m, BC = 70 m and AC = 85m

(i) Using a scale of I em to 10 m, make a scale drawing of the field.

(ii) From your scale drawing, find the actual distance from B to the point K, where K is equidistant from A, B and C.

Hint: Points on the perpendicular bisector of AB are equidistant from A and B.
