Question

The perimeter of triangle formed by the points (0,0), (2,0) and (0,2) is​

Answer 1

ABC is right angled triangle. As the 3 points lie in origin , x - axis and y- axis.

Perpendicular side = base side = 2 units.

(Hypotenuse)² = (Base)² + (perpendicular)²

(Hypotenuse)² = 2² + 2²

(Hypotenuse)²  = 4+4

(Hypotenuse)² = 8

Hypotenuse = √8

perimeter = sum of all sides.

perimeter = 2 + 2 + √8 = 4 + √8 units. = 4 + 2√2 units

hope it helps !!
