Answer:
A and C
Explanation:
Area is calculated by multiplying length times width. since a square has the same length and width it's simply 36.5*36.5. The 2 at the end is much more important the more advanced you get in mathematics, but basically the quilt is two dimensional, therefor it needs the two at the end.(a line is one dimensional and therefore doesn't need anything at the end and a cube is tree dimensional, so it would need a 3 at the end). Therefore 36.5*36.5 = 1332.25 and to show its a two dimensional area you add in².
The second question is similar. Multiply the length(9.3) by the width(also 9.3) dor 86.49. As explained above a two dimensional hole needs the two at the end. This question offers the answer in in or cm, you need to stick with whatever unit the question asked, in this case in.
