Answer 1

A+a+b=48, a=35/2
s=35/2 * (35/2+13)

Answer 2

Периметр не может быть в квадрате )))) 

Answer 3

Finding the Perimeter of a Rectangle

To find the perimeter of a rectangle, we need to know the lengths of its sides. In this case, we are given that one side is 13 cm longer than the other, and the perimeter is 48 cm.

Let's assume the shorter side of the rectangle is x cm. Since the longer side is 13 cm longer, it would be x + 13 cm.

The formula for the perimeter of a rectangle is P = 2 * (length + width).

Substituting the given values into the formula, we have:

48 = 2 * (x + (x + 13))

Simplifying the equation, we get:

48 = 2 * (2x + 13)

Now, let's solve for x:

48 = 4x + 26

4x = 48 - 26

4x = 22

x = 22 / 4

x = 5.5

So, the shorter side of the rectangle is 5.5 cm, and the longer side is 5.5 + 13 = 18.5 cm.

Finding the Area of the Rectangle

To find the area of a rectangle, we multiply the length by the width. In this case, the length is 18.5 cm and the width is 5.5 cm.

Using the formula A = length * width, we have:

A = 18.5 * 5.5

A = 101.75

Therefore, the area of the rectangle is 101.75 cm^2.
