Question

Show all work. 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

Answer 1

it's one half base times height, or (x + 6y)(x - 6y)/2 = (1/2)x^2 - 18y^2 sq. ft.
