Question

Периметр квадрата и прямоугольника и площадь тоже

Answer 1

Периметр квадрата равен a+a+a или 4a, периметр прямоугольника равен a+a+b+b или 2a+2b. Площадь квадрата равна a² или a*a, площадь прямоугольника равна ab

Answer 2

Perimeter of a Square

The perimeter of a square is the sum of the lengths of all its sides. Since a square has four equal sides, you can calculate the perimeter by multiplying the length of one side by 4.

Let's say the length of one side of the square is s. The formula to calculate the perimeter (P) of a square is:

P = 4s.

Perimeter of a Rectangle

The perimeter of a rectangle is also the sum of the lengths of all its sides. For a rectangle, the opposite sides are equal in length. Let's say the length of one side of the rectangle is a and the length of the adjacent side is b. The formula to calculate the perimeter (P) of a rectangle is:

P = 2a + 2b.

Area of a Square

The area of a square is the measure of the region enclosed by the square. It is calculated by multiplying the length of one side by itself. Let's say the length of one side of the square is s. The formula to calculate the area (A) of a square is:

A = s^2.

Area of a Rectangle

The area of a rectangle is also the measure of the region enclosed by the rectangle. It is calculated by multiplying the length of one side by the length of the adjacent side. Let's say the length of one side of the rectangle is a and the length of the adjacent side is b. The formula to calculate the area (A) of a rectangle is:

A = a * b.
