The expression 4 x 4x4, x gives the perimeter of a square with a side length of x xx units. What is the perimeter of a square with a side length of 5 7 7 5? start fraction, 5, divided by, 7, end fraction units?

P = 20/7 or 2 6/7

Step-by-step explanation:

We want to find the perimeter of a square

P = 4s where s is the side length

s = 5/7

P = 4 * 5/7

P = 20/7

We can leave it as an improper fraction or change it to decimal form

7 goes into 20 two times 2*7 = 14 20-14 = 6

The mixed number is 2 6/7
