 Question 363878: A gardener wants to create a triangular garden in the shape of a right triangle with shortest side length x – 6y ft. and the middle length side x + 6y ft. What is an algebraic expression for the area of the garden? Be sure to multiply this out and express in simplest correct mathematical form, including units. I thought I had this until I looked at the formula for a right triangle This is what I have (x-6y)(x+6y) using FOIL = x^2 - 36y^2 ft But how does this fit with a^2 + b^2 = c^2 Would I divide x^2 - 36y^2 by 2?
