One dad – who got A-levels in maths and economics, mind you – was completely thrown by his son’s homework.
He posted this pic on Facebook seeking for help with the answer, but everybody was just as bemused as he was!
The question asks to calculate the perimeter of two shapes.
The dad wrote: “My son’s grandma had spent a while helping him with his homework and most of it was straightforward but this one question left her stumped.”
“I then spent an hour or so trying to work it out but found it impossible.
The father continued: “I even sent it to a friend who got a 1st class degree in economics and they were baffled by it as well.
“A couple of friends are maths teachers too so I’ve sent it to them but so far I’ve heard nothing back.
“I really do think it is impossible and it is certainly not something a ten-year-old can answer.
Can you figure it out?
