Question

длина прямоугольника 14,5 см, а ширина в 1,3 больше. найти P и S помогитеее пожалуйста дам 50 балловв​

Answer 1

Для начала найдем ширину
b=14,5*1,3
b=18,85
P=14,5*2+18,85*2 или (14,5+18,85)*2
P=66,7
S=14,5*18,85
S=273,325

Answer 2

Calculating the Perimeter and Area of a Rectangle

To find the perimeter (P) and area (S) of a rectangle, we can use the following formulas:

1. Perimeter (P): - The perimeter of a rectangle is given by the formula: P = 2 * (length + width)

2. Area (S): - The area of a rectangle is given by the formula: S = length * width

Given: - Length of the rectangle = 14.5 cm - Width of the rectangle = 1.3 cm more than the length

Calculating the Width of the Rectangle

First, we need to calculate the width of the rectangle.

The width of the rectangle is 1.3 cm more than the length, so: - Width = Length + 1.3

Let's calculate the width: - Width = 14.5 + 1.3 - Width = 15.8 cm

Calculating the Perimeter (P)

Now that we have the length and width, we can calculate the perimeter using the formula: - P = 2 * (length + width)

Substitute the values: - P = 2 * (14.5 + 15.8) - P = 2 * 30.3 - P = 60.6 cm

So, the perimeter of the rectangle is 60.6 cm.

Calculating the Area (S)

Next, we can calculate the area of the rectangle using the formula: - S = length * width

Substitute the values: - S = 14.5 * 15.8 - S = 228.1 cm²

So, the area of the rectangle is 228.1 cm².

Therefore, the perimeter (P) of the rectangle is 60.6 cm, and the area (S) is 228.1 cm².
