Question

Длина прямоугольника 15 см, а ширина 7 см Найти периметр и площадь прямоугольника

Answer 1

1)Р=15см+15см+7см+7см=44(см)
2)S=15 х 7 =105 (см2)

Answer 2

P = (15 + 7) *2 = 44 (см)
S= 15*7= 105 (см²)

Answer 3

Calculation of Perimeter and Area of a Rectangle

To find the perimeter and area of a rectangle, we need to know the length and width of the rectangle. In this case, the length of the rectangle is 15 cm and the width is 7 cm.

Perimeter of a Rectangle

The perimeter of a rectangle is the sum of all its sides. For a rectangle with length (L) and width (W), the formula to calculate the perimeter (P) is:

P = 2(L + W)

Using the given values, we can substitute L = 15 cm and W = 7 cm into the formula:

P = 2(15 + 7) = 2(22) = 44 cm.

Therefore, the perimeter of the rectangle is 44 cm.

Area of a Rectangle

The area of a rectangle is the product of its length and width. For a rectangle with length (L) and width (W), the formula to calculate the area (A) is:

A = L * W

Using the given values, we can substitute L = 15 cm and W = 7 cm into the formula:

A = 15 * 7 = 105 cm^2.

Therefore, the area of the rectangle is 105 square centimeters.

In summary, the perimeter of the rectangle is 44 cm and the area is 105 cm^2.
