my question in (distance between two point)
rectangle QRST has an area of 6 square units, and Q is at the origin. R lies on the xaxis, T lies on theyaxis , and the coordinates of the vertices are whole numbers. what are the possible sets of coordinates of the rectangle ?

area=R*T
6=RT
r,t = (1,6); (6,1); (3,2);(2,3)
check that. 
i don't understand :(
