Marina is drawing a plan for a new garden. The rectangle plotted in the coordinate plane represents the garden, measured in feet. How much soil will she need to cover the garden?
10 ft2
12 ft2
20 ft2
24 ft2

The amount of soil Marina will need to cover the garden is:

24 ft2

Explanation:

The reason behind this is that the formula to obtain the area of a rectangle is L multiplied by W where L is the length and W width. Knowing this we can substitute the letters by the size of each representation, meaning L=6 W=4 we multiply them and we obtain 24 ft2. Because when the feet are multiplied they become square feet. Also, because it doesn't matter the spaces used in the direction of the cartesian plane the numbers in means or width and length are positive to obtain the measurement of the area.
