Question

Express the area of the entire rectangle

Answer 1

Answer:  $x^{2}+12x+35$

Step-by-step explanation:

In order to find the entire area of the rectangle, you have to first find the values of each quadrant, then you add the values together to find the answer. The top left quadrant is x times x, which is $x^{2}$. The top right value is x times 7, which is 7x. the bottom left value is x times 5, which is 5x, and the bottom right value is 7 times 5, which is 35. Put all the answers together and you get $x^2+5x+7x+35$, which simplifies to $x^{2}+12x+35$
