Let the unknown dimensions be a and b. Solve the two equations
a b = 5000
2a + 2b = 300
Simplify to a + b = 150 and substitute 150-a for b in the first equation.
a(150-a) = 5000
a^2 - 150 a + 5000 = 0
You could either solve by factoring or just see which of the multiple choices satsifies the two equations. There IS a solution.
