Question

Find the perimeter of the triangle formed by the pointz (0,0),(1,0), and (0,1)

Answer 1

area of a triangle: 1/2* base* height
height of triangle= 1unit
base of triangle= 1unit
area= 1/2* 1* 1 = 1/2 = 0.5 units

plz let me know if this is wrong

Answer 2

consider A (0,0),B (1,0),C (0,1)

=>AB=root(X2-X1)^2+(Y2-Y1)^2

=>AB=root (1-0)^2+(1-0)^2

=>AB=1

similarly,

BC=root2

and

AC=1

Perimeter=AB+BC+AC

=1+root1+1
=2+root2
