Revising geometry at present and came across this question
Using Pythagoras calculated length 6m for PQ length 15m for QR.
As far as length of PR I used Cosine Rule to achieve an answer of 20.42.
Used SAS rule to find area of triangle PQR and got answer 22.5 sq metres but seems too small visually
Please let me have your views
