20. Find the distance between the points A(8,-3) and B (09) by using distance formula​

Answer 1

Given:

(x1, y1) = A(8, -3)

(x2, y2) = B(0,9)

Formula

Distance between 2 points = sqrt((x2 - x1)^2 + (y2 - y1)^2)

Distance between A & B = sqrt((0 - 8)^2 + (9 - (-3))^2)

Distance between A & B = sqrt((8)^2 + (12)^2)

Distance between A & B = sqrt(64 + 144)

Distance between A & B = sqrt(208)

Distance between A & B = sqrt(13*16)

Distance between A & B = 4*sqrt(13) ——> Answer
