Asquare rug has an area 100 feet squared. write the side lengh as a square root. then decide if the side lengh is a rational number

De would be 100 feet
"100 square feet" would mean a square carpet would have sides of √100 = 10 feet
so, then 10 = 10/1 which is a rational number

13/3 is expressed in decimal format as 4.33333333... (the 3's are repeated indefinitely)
So, 13/3 is a rational number, but 4.33... can never be exactly the same as 13/3

You have 2 sides that are 2 cms and you have 6 sides that are 1/2 cm and you have 4 sides that are 1 cm. the smallest sides are 1/2 the medium sized sides are 1 and the smallest are 1/2. so to find the perimeter you have to add them all up together so your answer will be 11 cm's
