To find the area multiply the length by the width.
The length and width of a square are the same.
Area = 15 x 15 = 225 square feet.
A is the correct answer to this question because AC and BC differ because the B must be changed to an A.
What you want to do is add the probabilities up and divide by how many there are so it will be 0.4+1.8+0.2-0.8/4
Which is 0.35
