20 squares with perimeter 160, build together in one big square,and question is what will be the perimeter of the big square
20 squares with each perimeter 160.....
sqrt(160) - sqrt(20)
4 sqrt(10)- 2 sqrt(5)
not much more you can do but use a calculator
4 sqrt(10)- 2 sqrt(5)
not much more you can do but use a calculator
The calculation is correct, but the meaning is in error.
A square with perimeter 160 is 40x40.
A second problem is that you cannot arrange 20 equal squares into a square, since 20 is not a perfect square. How will you arrange them? A rectangle that is 4x5 will have sides 160x200 with perimeter 640, but it won't be a square.
