If you take 3.5 and divide it by 0.05, or times 20, that would make it 70.
A square has 4 equal sides
use pythagroeas theorem since a square has 4 right angles
a^2+b^2=c^2
a=b because the sides are equal (11)
11^2+11^2=c^2
242=c^2
square root both sides
11√2=c
the diagonal legnth is 11√2 centimiters
The efficiency of Franklin: 200/14 ft^2/hr
Scott: 200/10 ft^2/hr
So together: 200 / (200/14 + 200/10) = 5.83 hours
