I am stuck on the following NFER 11A q48 and 50
Q48
It’s a rectangle with bits cut off along 2 sides (Sorry I can’t draw the shape)
Length=x
Height =y
Shorter length=z
What is the parameter of this shape ?
2x + 2y
x + y + 2z
xy + zy
xy
x + 2y + x
The correct answer given is 2x + 2y
Q50

The first one - if there is a rectangle out of one corner it doesn't change the perimeter only the area.
They will meet every six days because 6 is the smallest number 2 and 3 both go into [the lowest common multiple].
We are told they meet twice in the first week - this must be day 1 and day 7 so next meetings are day 13 [7 + 6], day 19 [13+6] and day 25 [day 19+6].
Hope this helps!
