I think we have found them and cared for them I don't think it's right b/c I guessed.
the answer is 5.10729613...
Step-by-step explanation:
A=140sq. units
N x (4/5) = (3/4)
(4/5)N = (3/4)
Divide both sides by 4/5 (cross multiply, 3 times 5, 4 times 4)
N=15/16 = 0.938
Its the 10th place because its the first number on the decimal side
