Triangle ABC is a right triangle (why?), the length of CA is 10 and the length of AB is 6. Use Pythagoras theorem to find the length of BC. Use a similar argument to find the length of CD. Now you know the lengths of the parallel sides of a trapezoid and the distance between the parallel sides. What is its area? Penny
