A. square root of 89
B. 5
C. 8
D. square root of 39

Answer 1

use the coordinates for each vertex to get their distance \(\bf \textit{distance between 2 points}\\ \quad \\
d = \sqrt{(x_2-x_1)^2 + (y_2-y_1)^2}\)

Answer 2

hmm.. wait.. is the diagonals.. meh

Answer 3

well. you'd still need their distance =)

Answer 4

d?
