Answer:
The area of a rectangle is the product of its width and length.
[tex]A=w\times L[/tex]Now, in our case, the width is the vertical distance of the rectangle and it is found by counting the boxes from (-8, -4) to (-8,6). There are 10 boxes from the given points; therefore the width of the rectangle is w = 10.
Now the length is the distance between (-8,-4) and (6, -4). Counting the boxes we find that there are 14 boxes; therefore, L = 14.
With the value of width and length in hand, we now calculate the area
[tex]A=10\times14=140[/tex]Hence, the area of Jamal's deck is 140 square units.
