Answer:

Then length of diagonal is 5√(2)

Step-by-step explanation:

Perimeter(p)=20

Perimeter of square(p)=4xLength(L)

20=4 x L

Divide both sides by 4

20/4=4L/4

5=L

L=5

Length of diagonal=√(5^2+5^2)

Length of diagonal=√(5x5+5x5)

Length of diagonal=√(25+25)

Length of diagonal=√(50)

Length of diagonal=√(25x2)

Length of diagonal=√(25)x√(2)

Length of diagonal=5x√(2)

Length of diagonal=5√(2)

What is the value of pie and how can I round it to the nearest tenth
Orlov [11]

The Value of Pi is actually an infinite number and cannot be calculated. It is not a real number. Usually many just shorten Pi to the decimal 3.14, which it is most commonly used as since there is no exact decimal of Pi.

(a). Three pairs add to 4 1,3 2,2 and 3,1 so P(4) = 3/36 = 1/12

(b). 6 pairs add to 7 so P(7) = 6/36 = 1/6

(c) 15 pairs add to less than 7 so P(<7) = 15/36 = 5/12
