Answer 1

Answer:

Fourth (last) rectangle has an area of 18 square units

Step-by-step explanation:

$l = 1 - ( - 5) = 1 + 5 = 6 \: units \\ w = 1 - ( - 2) = 1 + 2 = 3 \: units \\ area = lw = 6 \times 3 = 18 \: {units}^{2}$

Answer 2

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!
