The perimeter is adding all the outside edges together:
4 + 1 +4 +1 + 3 + 1 = 14 cm.
A tessellation is the regular t<span>iling of a plane shape</span>
I got 20.89, and nearest to the whole number would be 20.
The way to work this out is to find a common denominator. so in this case 80 is a common denominator. So it would be 3/8 into 30/80 and then 4/10 into 32/80 therefore 4/10 is bigger
