उत तर:
# => d = 3 वर ग (2) #
स पष ट करण:
द र स त र:
# => d = sqrt ((y_2-y_1) ^ 2 + (x_2-x_1) ^ 2) #
हम द रह ह:
# => (x_1, y_1) = (2,5) #
# => (x_2, y_2) = (5,2) #
इसल य, #d = sqrt ((2-5) ^ 2 + (5-2) ^ 2) #
# => d = sqrt ((- 3) ^ 2 + (3) ^ 2) #
# => d = sqrt (9 + 9) #
# => d = sqrt (18) #
# => d = sqrt (9 * 2) #
# => र ग (हर) (d = 3sqrt (2)) #
