Please explain your answer for the attached question.

What I am having difficulty understanding is the easier way of calculating the Perimeter of the square.

I know it is 4s, but with the figure attached, I was not able to calculate within the 2 mins time frame.

Thanks a bunch

I got 7/3 as my answer:

perimeter is not 4s it is 14s. You are counting the whole squares. you need to count the sides of the figure as a whole

6s^2 = 14s

6s^2 - 14s = 0

2s(3s -7) = 0

s = 7/3

What I meant was that perimeter of 1 square is 4s, not all the 6 squares. I still don't understand how you got 14s.
Shouldn't the Perimeter be calculated as?
6*(4s) - shared sides = 24s - 10s ? How do you deduce 10s?

Apologies for the slower brain activity... :oops:

@kanha...

it is perimeter.. y you are subtracting shared sides... just add outer sides and those are 14 in nos...

Ok lets start with the top square and work our way clockwise:

1st square has 3 outer boundary sides: 3s
2nd square has only 2 outer boundary sides: 2s
3rd square has 3 outer boundary sides: 3s
4th square has only 1 outer side: 1s
5th square has 3 outer boundaries: 3s
6th square has 2 outer sides: 2s

3+2+3+1+3+2 = 14s

perimeter is just the outer boundary of a figure as a whole. I think you are adding 3 more sides (which are shared by the other squares).

Hopefully that clarifies a it a little.
