Let ABC be the triangular plot
Let AB = c = 3x m; BC = a = 5x m; CA = b = 7x mNow, perimeter of ∆ABC = 300 m⇒a + b + c = 300⇒5x + 7x + 3x = 300⇒15x = 300⇒x = 20So, a = 5×20 = 100 m; b = 7×20 = 140 m; c = 3×20 = 60 mNow, semi-perimeter, s = 3002 = 150 mNow, area = ss-as-bs-c=150150-100150-140150-60=150×50×10×90=3×5×5×3×3×10×10×10×10=3×5×10×103=15003=1500×1
