Answer:

The fourth rectangle.

Step-by-step explanation:

The first rectangle has one side with length 1-(-1)=2 units, and another side with length 3-(-3)=6 units. Multiplying these two side lengths together, you get a total area of 12 units squared. For the second rectangle, it has one side length of 2 units and another of 7 units, which is a total area of 14 units squared. For the third rectangle, it has one side with length 4 units and another side with length 5 units, which is a total area of 20 units. This leaves us with the last rectangle, which has side lengths of 3 and 6 units. 3*6=18, meaning that the fourth rectangle is the one with an area of 18. Hope this helps!

area paralllogram is
10 times 3 because 3 is height and 10 is base length or 30
