For the Q on the sqr, we can know that one side of the shaded sqr is 48/4=12cm. At the same time, one length and one breath of the rectangle has the length of 20cm.
BY OBSERVATION,
the length of a rectangle is equals to one side of the sqr and one breath of a rectangle. Hence,
side of sqr+2breadth=20
12 + 2 breadth = 20
2 breadth =8
breadth = 4
length = 4+ 12 = 16cm.
It's so clear to explain to my gals on this format and she understands it clearly, thanks again

Lets say P has 1 unit of stamps. Then J will have 12 more than 1 unit of stamps. Given that T has 4 times as much as J, T will have 48 more than 4 units of stamps. In total, T J and P will have 60 more than 6 units of stamp.
60 + 6units = 246
6units = 186
1 unit = 32.
So J has 32+12=44 stamps.
