Answer:

The total area of the two rectangles is
$(5x^(2) +7x)\ units^(2)$

Explanation:

Area of rectangle 1

$(x)(3x+1)=(3x^(2) +x)\ units^(2)$

Area of rectangle 2

$(2x)(x+3)=(2x^(2) +6x)\ units^(2)$

therefore

The total area of the two rectangles is equal to

$(3x^(2) +x)\ units^(2)+(2x^(2) +6x)\ units^(2)=(5x^(2) +7x)\ units^(2)$
