Question

distance between the points A(2,3) and B(4,1)

Answer 1

$\text {Distance = }\sqrt{(Y_2-Y_1)^2 + (X_2 - X_1)^2}$

.

$\text {Distance = }\sqrt{3 - 1)^2 + (2-4)^2}$

$\text {Distance = }\sqrt{2^2 + (-2)^2}$

$\text {Distance = }\sqrt{8}$

$\text {Distance = }2\sqrt{2} = 2.83 \text { units}$

Answer 2

(2,3) and (4,1)
x1=2, y1=3 and x2=4,y2=1
now under root
/(x2-x1) (y1-y2)
/(4-2) (3-1)
/2*2
