Solution
The area of a rectangle is calculated by multiplying the length by the width.
In this case, the tree house floor is a rectangle with vertices at J(1, 1), K(1, 8), L(9, 8), and M(9, 1).
The length of the rectangle can be determined by the difference in the x-coordinates of J and M, which is 9 - 1 = 8 feet.
The width of the rectangle can be determined by the difference in the y-coordinates of J and K, which is 8 - 1 = 7 feet.
Therefore, the area of the tree house floor is 8 feet * 7 feet = 56 feet^2.
So, the answer is a. 56 feet^2.
