Question

Which expression shows the exact perimeter of the square?
A. 4 x sqrt 34
B. 4 x sqrt 8
C. 4 x sqrt 6
D. 4 x sqrt 2

Answer 1

A. 4 x sqrt 34

Answer 2

Given the two points (x1, y1) and (x2, y2), the distance between these points is given by the formula:\[d=\sqrt(x _{2}-x _{1})^{2}+(y _{2}-y _{1})^{2}\] Note that the entire right side is under the square root, not just a portion. Anyway, plug two of your points in that form a line in your graph, and you'll return a value. 4(sqrt(something))
