Let ABC be a triangle of area 24 sq. units and PQR be the triangle formed by the midpoints of sides of △ABC. Then the area of △PQR is
Area of △ABC = 24 sq. units.
∵ Q and R mid points of AB and AC
∴ RQ || BC and RQ=12BC
Similarly, PQ||AB and PQ=12AB
And, RP || AC and RP=12AC
∴ area of △PQR=14 Area of △ABC
=14×24=6 sq. units
