Let the feet of the perpendiculars from the point $ P (5, 1, -3) $ on the lines $ L_1 $ and $ L_2 $ be $ Q $ and $ R $ respectively. If the area of the triangle $ PQR $ is $ A $, then $ 4A^2 $ is equal to:

Notice that 18 has one factor that is a perfect square: 9, and that: 9 x 2 = 18 Since 9 x 2 equals 18, the two numbers that we are going to use for Step 2 are 9 and 2. Step 2: Split the product using two square root symbols. For the second step, we can use the factors from Step 1 to rewrite √18 as follows: √18 = √ (9 x 2) = √9 x √2
