Provide an appropriate response.Find the area of the given figure.
A. 3.75 mm2 B. 4 mm2 C. 7.02 mm2 D. 14.04 mm2
Provide an appropriate response.Consider the following figure, which is a square divided into two squares and two rectangles.
The length of each side of the large square is x + 5, which means that the area of the largest square is (x + 5)2. Use the formulas for the area of a square and the area of a rectangle to write the area of the largest square as a trinomial that represents the sum of the areas of the four figures that comprise it.
A. x2 + 10x + 25 B. x2 + 5x + 25 C. x2 - 2x + 25 D. x2 + x + 25
