In triangle PQR, let M be the midpoint of QR, let N be the midpoint of PR, and let O be the intersection of QN and RM, as shown. If QN perp PR, QN = 12, and PR = 14, then find the area of triangle PQR.
+2666 Because QN is a perpendicular midpoint, it is basically an altitude
We also know the base is 14, so the area of the triangle is \(12 \times 14 \div 2 = \color{brown}\boxed{84}\)
