applications of polynomial equations

[Mrs.Leah]

I have a hard time formulizing applications. I need to know how to set up this. A triangle sail is 9m taller than it is wide. Find the height and the base of the sail. The area is 56m^{2 .}

I have a hard time formulizing applications. I need to know how to set up this. A triangle sail is 9m taller than it is wide. Find the height and the base of the sail. The area is 56m^{2 .}

What have you tried? You drew a triangle with its base (the width) at the bottom, you drew the height line up the middle, and you labelled the two dimensions with the standard variables. You noticed that the height ("taller") is defined in terms of the base ("wide"). You created an expression to represent this definition. You plugged all of this into the "area" equation, along with the given value for area.

Then what? Please be complete. Thank you!
