The given sides are 12 cm, 15 cm and 21 cm
Shortest side is 12 cm
As given that in real the shortest side is 200 m
So 12 cm=200 m
then 1 cm = [tex]\frac{200}{12}=\frac{50}{3}[/tex]
Hence 15 cm = [tex]\frac{50}{3} * 15 = 250[/tex] m
21 cm = [tex]\frac{50}{3} * 21 = 350[/tex] m
So,,
15 cm in the photograph is 250 m long
.
21 cm in the photograph is 350 long.
