Suki used a 10 foot length of fencing as two sides of the border of a triangle garden as shown above, where a wall is the third side of the border. If the side of the fence perpendicular to the wall is x feet long, what is the length, in feet, of the side of the border formed by the wall?

10-2x

10+2x

100-20x (all under square root thing)

100-20x + x^2 (also under square root)
