Lets break it down:
The bottom right picture shows an approximation of what 1 wingspan length is, and the goal is to estimate lengths.
A. 1 wing is approx. 7 meters. To find the wingspan of the plane just do 7 meters multiplied by 2 = 14 meters (approx wingspan). Now we convert (remember, to the nearest foot!)
14 meters = 45.93 ft
Round it to the nearest foot = 46 ft is your approx. wingspan.
B. The height. This is one is a little tricky! Lets try to use what we know:
1 wing is approx. 7 meters. Since these are approximations, lets say half of one wing is roughly the size of the height of the plane. Since these are approximations I'd say 4 meters.
4 meters = 13 ft (rounded).
I checked online for the specs of the Lysander and the exact height is 14 ft 6 in and wingspan is 50 ft. This means our approximations were correct!
C. The length would be 10 ft + 7 meters
10 ft = 3 meters (rounded)
3 meters + 7 meters = 10 meters
(converting to meters then to ft at the end because it's less messy)
10 meters = 33 ft (rouned)
length of the Lysander is approx. 33 ft!
(the real length is 30 ft 6 in)
This means our approximations were correct once more.
Hopefully this helped you and made your night/day easier.
