area of picture = (4x+3)(3x+5)
= 12x^2 + 29x + 15
area of whole thing = (4x+3 +4)(3x+5 + 4)
= (4x+7)(3x+9)
= 12x^2 + 57x+63
area of border
= 12x^2 + 57x+63 - (12x^2 + 29x + 15)
= 28x + 48
= 12x^2 + 29x + 15
area of whole thing = (4x+3 +4)(3x+5 + 4)
= (4x+7)(3x+9)
= 12x^2 + 57x+63
area of border
= 12x^2 + 57x+63 - (12x^2 + 29x + 15)
= 28x + 48
