Answer #1

Coordinates of point-L is (1,1)

And coordinates of M is (6, - 3)

Distance between two coordinates is given by -

D = ((x2 - x1)2 + (y2 - y1)2)1/2​​​​​​

= ((6-1)2 + (-3 - 1)2)1/2​​​​​​

D = 6.4

Side of traingle (D) = 6.4

Perimeter = sum of all sides = 10+6.4+6.4 = 22.8

Option (C) is correct
