Question

1. A find the distance between the points
A(7,-1) and B(3,2)
nr ad Q52).​

Answer 1

Answer:

A(7, -1) , B(3, 2) ,........ (Given points)

Let A (7.-1) be x1, y1

and B(3, 2) be x2, y2

since,

We know that,

Distance formula=√ (y2-y1) ²+(x2-x1) ²

therefore, by substituting the values,

d(A, B) =√(2+1) ²+(3-7) ²

=√3²-4²

=√9+16

=√25

=5

therefore, d(A, B) =5 units
