To find the length of the puma in the drawing, we can use the concept of scale. The given scale is 1 cm : 0.5 cm, which means that for every 1 cm in the drawing, it represents 0.5 cm in real life.
Now, we need to find out how many centimeters in the drawing represent the actual length of the puma (2.45 m = 245 cm).
We can set up a proportion using the scales:
1 cm in the drawing / 0.5 cm in real life = x cm in the drawing / 245 cm in real life
Simplifying the proportion, we get:
1 / 0.5 = x / 245
2 = x / 245
To find x, we can cross-multiply:
2 * 245 = x
x = 490
So, the length of the puma in the drawing is 490 cm. To round it to the nearest tenth of a centimeter, it would be 4.9 cm.
Therefore, your answer of 4.9 cm is correct.
