W=2L-3 W*L=193 replace W with 2L-3: (2L-3)L=193 2L^2-3L-193=0 Cannot factor are you sure the numbers are correct? If it cannot be factored, use the quadratic formula to find out L, then you can find out W use the Pythagorean theorem to find the diagonal. I don't see an easier way.
The top question should be greater than or equal to. not just greater than. so the circle should be closed. and as for the direction, it should be a closed circle on 13.50 pointing towards the right
