Question
On a map drawn to a scale of 1:25000, a triangular plot of land is right angled and the sides forming the right angle measure 225cm and 64cm.Find: The actual length of the sides in km
Solution
Scale = 1:25000
Let AB = 225cm and BC = 64cm
Actual length of AB -
= `(225 xx 25000)/(100 xx 1000)`km
= `(5625)/(100)`km
= 56.25km
Actual length of BC -
= `(64 xx 25000)/(100 xx 1000)`km
= `(16)/(100)`km
= 16km.
