Step-by-step explanation:
Answer:
6.2 meters
Step-by-step explanation:
1) area = l*w
74.4 = 12x
x=6.2
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 = 
Hence 15 cm =
m
21 cm =
m
So,,
15 cm in the photograph is 250 m long
.
21 cm in the photograph is 350 long.
250 mg / 100 mg = 2.5 ml
5 ml / 2.5 ml = 2
1/2 teaspoon
0.4 meters. Hopefully this helps
