SATs are still on, but I managed to persuade my son to study a bit on his own. He did some mental maths- got all the questions right.
Hint: discuss with your child, what is the area of a shape if you know the area of a whole circle and an angle in unknown shape. e.g. 72 degrees It's just a part of a circle. What fraction is this part? How can you calculate its area if you know the area of the whole circle?
