PQ = <1,1,-9> -> PR= -> -> PQX PR= <26,19,5> (b) Using your answers to (a), compute the area of the triangle APQR. Area of triangle = (c) For an alternate way to find the triangle area,. square units use dot products instead to find the angle measure mZP between PQ and PR, then compute the area with the formula (You should get the same area this way!)
