Question from rohan, a student:

i have a diagram with a triangle inside a trapezoid. trapezoid is PQRS ,
PQ being the line above and RS THE LINE BELOW.The area of this is 12.
If RS is twice PQ what is the area of PQS.


I assume that PQ and RS are parallel. I can help you get started

  1. What is the area of a trapezoid?

  2. Join Q to M, the midpoint of RS.


  1. What do you know about triangles PQS and SQM?

  2. What is the area of triangle QRM
If you need more help write back,
