Question

Help me solve this Algebraic word problem. Assistance will be appreciated.

Answer 1

Big A: x^2+12x+36

Little A: x^2

Combined: 2x^2+12x+36

Area of little walkway is: 12x + 36

Explanation:

Big A: (x+6)(x+6) => Multiply using FOIL => x^2+12x+36

Little A: (x)(x) => Multiply => x^2

Combined: (x^2+12x+36)+(x^2) => Combine like terms => 2x^2+12x+36

Area of little walkway is: (x^2+12x+36)-(x^2) => subtract like terms => 12x+36
