Area of rectangles(A+B+C+D) =3x+7x+x *x +7x
                                             $$=3x+21+x^2 +7x = x^2 +10x+ 21$$

anonymous · Answer

can you explain how they are related and why this is so

anonymous · Answer

Area of the larger rectangle = (x+7)(x+3)$$=x^2 +3x+7x+21 =x^2+10x+21$$

Therefore from the two results we can say that:

Area of rectangles(A+B+C+D) =Area of the larger rectangle
