Answer:
C.
Step-by-step explanation:
We know that the area of a square = side ²
Therefore, for a known area A, the side length is
side = √ (area)
= √ (175)
= 13.2288 (to 4 places of decimals).
7 mm x 9mm x 12mm = 756mm
To get this answer you have to multiply 9 and 12 which would be 108. Then you have to divide 108 on both sides to get mm by itself. 756 divided by 108 is 7 which is the answer!
