Two perpendicular line segments divide a large rectangle
into 4 small rectangles. The areas of 3 of these 4 small
rectangles are shown. What is the area of the other small
rectangle?  Choose one: A) 12 B) 13 C) 14 D) 15 E) 16
Label the 4 small rectangles R1, R2, R3, and R4 so that the areas of R1, R2,   and R3 are 8, 6, and 9 respectively and R4 is the rectangle whose area we want to find.   Denote the area of R4 by x. Then 8 · 9 = 6 · x. (Note that R1 and R2 have the same   base and so do R3 and R4. 12lso, R1 and R4 have the same height and so do R2 and   R3.)   correct answer 12
