First, you must find the area of 1 of the parallelograms.
The formula for this is bh, or base times height.
.28 • .34 = .0952
Now, multiply the area of 1 of the parallelograms by the amount of how many there are.
.0952 • 9500 = 904.4
This means the answer is that the area of the floor is 904.4 meters squared.
