The points (-1,4) and (2,-8) are adjacent vertices of a square. What is the area of the square?

Use distance formula to find the distance between the two points....this is the side length of the square....then area = side X side

 

d^2 = ( -1 -2)^2 + ( 4 - -8)^2        solve for d  ( the side length) cheeky
