urgent help 4 maths paper 4
astarmathsandphysics:
The base of the trapezium is 3 times the base of the triangles, so cut the trapezium up into 3 equal triangles and EVERY triangle has the same area whether shaded or not.
twilight:
divide the shaded trapezium into 3 triangles
now all the small triangles would be equal .. so the % would be 3/5 x 100 = 60%
the 3 is the shaded and the 5 is the total number of triangles
godfather93:
how do you know the base of the trapezium is 3 times the base of the triangles?

how can you be so sure this question won't come up? You never know what may come up and it's better to clear your doubts before the exam.

and by the way this is no silly question cause it is challenging and not many people can do this question.
