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

Answer 1

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.
