Question

Длина прямоугольника 18см.Ширина составляет 6 часть длины. Найти периметр и площадь

Answer 1

1)18:6=3(см)-ширина прямоугольника.
2)P=(a+b)*2; P=(18+3)*2=42(см)-периметр прямоугольника.
3)S=a*b; S=18*3=54(см)-площадь прямоугольника.

Answer 2

Given Information

The length of the rectangle is 18 cm, and the width is 6 parts of the length.

Calculating the Perimeter

To find the perimeter of a rectangle, we add up all the sides. In this case, we have two sides of length 18 cm and two sides of length 6 parts of the length.

Let's calculate the perimeter step by step:

1. The length of the rectangle is 18 cm. 2. The width is 6 parts of the length, which means the width is (6/1) times the length. 3. Therefore, the width is 6 * 18 cm = 108 cm.

Now, we can calculate the perimeter:

1. The perimeter of a rectangle is given by the formula P = 2 * (length + width). 2. Substituting the values, we get P = 2 * (18 cm + 108 cm). 3. Simplifying, we have P = 2 * 126 cm. 4. Therefore, the perimeter of the rectangle is 252 cm.

Calculating the Area

To find the area of a rectangle, we multiply the length by the width.

Let's calculate the area:

1. The length of the rectangle is 18 cm. 2. The width is 6 parts of the length, which means the width is (6/1) times the length. 3. Therefore, the width is 6 * 18 cm = 108 cm.

Now, we can calculate the area:

1. The area of a rectangle is given by the formula A = length * width. 2. Substituting the values, we get A = 18 cm * 108 cm. 3. Simplifying, we have A = 1944 cm^2.

Therefore, the area of the rectangle is 1944 square centimeters.

Summary

- The perimeter of the rectangle is 252 cm. - The area of the rectangle is 1944 cm^2.
