Pythagorean Theorem is not part of the P6 curriculum. For Primary 6 students to understand how to solve this, you need to rotate Square PQRS until P becomes the midpoint of AD, S the midpoint of side DC, R the midpoint of BC and Q the midpoint of AB. Then, if you draw a line from P to R and from Q toS, you will notice that Square PQRS becomes divided into 4 equal parts while Square ABCD is divided into 8 equal parts (ignore the circumference of the circle.) Since PQRS is made up of 4 identical triangles and ABCD is made up of 8 identical triangles, you can conclude that the area of ABCD is twice of that of PQRS. Hope it helps.. :)

Yup, it is 128 and familiarity with squares and inscribed squares actually help especially in making measurements. The additional information about the circle may help but it would require a few more steps:-)

Since the number of leftover sweets when put into packets of 3 or 4 are the same, we can safely conclude that the number of leftover sweets when placed into packets of 12 is the same. So just list down the multiples of 12, and the multiples of 7. Then choose the pair where the multiple of 12 is just 1 LESS than the multiple of 7.

Multiples of 12 : 12, 24, 36, 48 ...

Multiples of 7 : 7, 14, 21, 28, 35, 42, 49 ....

Notice 48 is 1 less than 49. So the least number of sweets to make the situation possible is "49".

36 can be put nicely into packet of 3 and 4 with no leftover!I'm confused now!

36 is not a multiple of 7. In this case, it's 49.

need help with this p3 question: Liying and Sufia had an equal number of stamps. Liying bought another 300 stamps and Sufia gave away 252 stamps. After that, Liying had five times as many stamps as Sufia. How many stamps did Sufia have in the end?
