Online "^" is used to indicate an exponent, e.g., x^2 = x squared.
Online, “*” is used to indicate multiplication to avoid confusion with “x” as an unknown.
Area = length * width
7.7682*10^4 = Length * 2.42*10^2
(7.7682*10^4)/(2.42*10^2) = Length
When multiplying/dividing, add/subtract exponents respectively.
Solve for length.
