Answer:
Let rectangle be ABCD and the point A is 4,1 ; B is 7,4; C is 13, -2 and D is a,b
For a rectangle, mid point of diagonal are same.
midpoint of AC = 4+13 /2 , 1-2 /2 = 17/2, -1/2
midpoint of BD = a+7 /2 , b+4/2
a+7 /2 =17/2
a+7=17
a=10
similarly, b+4 / 2 = -1/2
b+4=-1
b = -5
The fourth co-ordinate of rectangle is (10,-5)
