In APQR, M, N, and S are the mid-points of sides PQ, PR, and QR, respectively. The area of ΔPORis 46 cm2.
we know that:-
The area of a triangle formed by joining the mid-points of two sides of a triangle is one-fourth the area of the original triangle.
The area of the quadrilateral formed by mid-points of sides and one vertex is half the area of the original triangle.
so procedding with above formula:-
The mid-points M, N, and S divide ΔPQR into four smaller triangles of equal area.
Area of ΔPOR =46 cm2
Area of each smaller triangle = 46 /4
= Area of each smaller triangle = 11.5cm2
The quadrilateral MNRQ consists of three of these smaller triangles.
Area of quadrilateral MNRQ =3 X 11.5=34.5cm2
Option (d) is the correct answer.
