Find the distance between the points.  R(a+b, a-b) S(a-b, a+b).,solve coordinate geometry

Answer»

Distance between two points (x1,y1) and (x2,y2) is

D = √((x2-x1)2 + (y2 - y1)2)

So, given points are R(a+b, a-b), S(a-b, a+b)

D = √(((a-b)-(a+b))2 + ((a+b)-(a-b))2)

D = √((-2b)2 + (2b)2)

D = √(4b2 + 4b2)

D = √(8b2)

D = 2√2b

Therefore, distance between them is 2√2b
