Before we solve, let's define what the area formula is. The area means to multiply the length by the width.
Now that we've defined what area is, let's solve.
14 1/2 x 13 1/4.
This is a little complicated, so I prefer that we convert our fractions into decimals.
14 1/2 = 14.50
13 1/4 = 13.25
Now we can multiply properly.
14.50 x 13.25 = 192.125
Remember, since our shape is 2-Dimensional, our units are ^2.
Your area is:
192.25 ft^2
I hope this helps!
