After classroom learning was replaced by online lessons more than two months ago, Hong Kong’s secondary students are desperate to return to school to reunite with their dearly missed teachers and friends. Some told Young Post that they are even thinking about people they aren’t very close with, or they never thought they would miss. Here are some amusing, endearing and heartfelt confessions from eight local and international students.
I miss my history teacher. He always encourages us to study – he talks about how hard he worked to earn his place at university – and reminds us that the DSE is all about having the right frame of mind and perseverance. There were times where I found him to be a bit annoying because he can be really talkative, but now I realise how much I need his motivational speeches because I am anxious – and lacking confidence – about my DSE. I need someone like him to walk me through this difficult time.

Explanation:
side of equilateral triangle = 12
perimeter = 12 ×3
= 36
perimeter of equilateral triangle = perimeter of square ( because the wire is reshaped not its size.)
36 = 36
perimeter of square = 4 × side of square
36 = 4 × side of square
side of square = 36 / 4
