The side of a square is 2 and 7/2 inches. use the area formula a=s2 to determine the area of the square. 1. a= 196 square inches 2. a= 128 square inches 3. a= 49 square inches 4. a= 4 square inches *will give brainleist answer*

2 to the power of (7/2) can be written as sqrt (2^7), since the 2 on the bottom of the exponent can be turned into a root.

Then, since sqrt (2^7) is the side length, we square it to get the area. If you square a square root, they cancel out, so you are left with 2^7 = 128 inches squared.

The answer is choice (B).

answer: given that the roller coaster can accommodate 1600 riders per hour, thus the roller coaster can accomodate 1600 / 60 = 26.67 riders per minute.

given that there are 345 people in the line, the number of minutes it will take for the 345 persons to get into the roller coaster is given by 345 / 26.67 = 12.94 minutes.

therefore, it will take you 12.94 minutes to get to the front of the line.
