Question

On a map drawn to a scale of 1:25000, a rectangular plot of land has sides 12cm x 16cm. Calculate: The area of the plot in sq km

Answer 1

scale = 1:25000
Area ABCD 
= 12 x 16 x 25000 x 25000cm² 

= `(12 xx 6 xx 25000 xx 25000)/(100 xx 1000 xx 100 xx 1000)`km

= `(120000)/(10000)`km²
= 12km².
