Question

IF A, B, C are the mid point of sides of triangle PQR , Find ar PQR class 10​

Answer 1

Answer:

area of triangle PQR =1/4th of area of triangle ABC

so,

1/4th of triangle ABC =1/4(1/2(1(2-1)+1(1-0)+0(0-2))

=1/4(1/2(1+1))

=1/4(1/2×2)

=1/4(1)=1/4 sq.units

Therefore area of triangle PQR is equal to 1/4 sq.units

(This problem is solved with help of area of triangle in coordinate geometry) I think this answer will help us ,if there are any mistakes please excuse me.
