Answer 1

1) 20 1/2:4=5 1/8=5.125 (м)
Ответ: 5.125 м или 5 1/8 м (одно и тоже, записывай как тебе нужно-в десятичных или обыкновенных дробях)

Answer 2

Perimeter of a Square

To find the length of a side of a square given its perimeter, we can use the formula for the perimeter of a square, which is P = 4s, where P is the perimeter and s is the length of a side.

In this case, we are given that the perimeter of the square is 20 1/2 m. To find the length of a side, we can rearrange the formula and solve for s:

P = 4s

20 1/2 = 4s

To solve for s, we divide both sides of the equation by 4:

s = (20 1/2) / 4

Now, let's calculate the length of a side of the square:

s = 20 1/2 / 4

To perform the calculation, we need to convert the mixed number 20 1/2 to an improper fraction. The improper fraction equivalent of 20 1/2 is 41/2:

s = 41/2 / 4

To divide a fraction by a whole number, we multiply the numerator by the reciprocal of the denominator:

s = (41/2) * (1/4)

Multiplying the numerators gives us:

s = 41/8

Therefore, the length of a side of the square is 41/8 meters.
