Answer 1

27,2:4=6,8 --- одна сторона 
6,8*6,8=46,24---- площадь
46,24 = 46,2 ---- округлили до десятых 

Answer 2

Perimeter of a Square

To find the perimeter of a square, we need to know the length of one side of the square. In this case, the perimeter of the square is given as 27 whole centimeters and 2 centimeters.

Let's assume that the length of one side of the square is represented by the variable a.

Calculation

The perimeter of a square is given by the formula: P = 4a, where P is the perimeter and a is the length of one side.

Given that the perimeter is 27 whole centimeters and 2 centimeters, we can set up the equation as follows:

27 + 2 = 4a

Simplifying the equation, we have:

29 = 4a

To find the length of one side, we divide both sides of the equation by 4:

a = 29/4

Finding the Area

To find the area of a square, we need to know the length of one side. In this case, we have already found that the length of one side is 29/4.

The area of a square is given by the formula: A = a^2, where A is the area and a is the length of one side.

Substituting the value of a into the formula, we have:

A = (29/4)^2

Simplifying the expression, we get:

A = 841/16

To round the answer to the nearest tenth, we divide 841 by 16 and round the result to one decimal place:

A ≈ 52.6

Therefore, the area of the square is approximately 52.6 square centimeters.

Please note that the calculations are based on the assumption that the given perimeter is accurate.
