Answer: A. 384 sq. mm
Step-by-step explanation: The area for the square is 12x12 or 144. The area for a triangle is base x height x 1/2. Therefore, that would be 12 x 10 x 1/2 or 60. There are 4 sides to this pyramid, so 60 x 4 = 240. We then add 144 and 240 to get 384 sq. mm.
To compare the two fractions you could graph the two fractions on a number line and compare which one is greater, and which is less.
Or you could make the two fractions have the same denominator and then compare the numerator. If the numerator for one is greater than the other, than that fraction is greater.
Hope this helps :)
