Question

Find the area of triangle whose vertices are P(-1,1), Q(0,5), and R(3,2)

Answer 1

Step-by-step explanation:

LETS FIND OUT THE SIDES BY DISTANCE FORMULA,

PQ= sq.root of 17

QR= sq.root of 18

PR= sq.root of 17

(as 2 sides are equal , it forms an isoceles triangle

so find the area by formula).
