Question 4
The distance between the points (0, 5 ) and ( - 5, 0) is:
(A) 5
(B) $5\sqrt{2}$
(C) $2\sqrt{5}$
(D) 10

Answer 1

$\because \text{Distance between the points}(x_1,y_1)and(x_2,y_2),d=\sqrt{(x_2-x_1{)}^2+(y_2-y_1{)}^2}Here,x_1=0,y_1=5and{x}_2=-5,y_2=0\therefore \text{Distance between}Points(0,5)and(-5,0)=\sqrt{(-5-0{)}^2+(0-5{)}^2}=\sqrt{25+25}=\sqrt{50}=5\sqrt{2}$
