Question

Ширина прямоугольника ровна 8 см а Площадь ровна 160 см квадрата найти Периметр и длину

Answer 1

Ширина-8 см
Длина-? см
S- 160 см в квадрате
P-? см

160:8= 20(см)- длина
20*2+8*2= 56(см)- периметр

Answer 2

Problem Analysis

We are given the width of a rectangle, which is 8 cm, and the area of the rectangle, which is 160 square cm. We need to find the perimeter and length of the rectangle.

Solution

To find the length of the rectangle, we can use the formula for the area of a rectangle: Area = Length × Width. We can rearrange this formula to solve for the length: Length = Area / Width.

Let's substitute the given values into the formula: - Width = 8 cm - Area = 160 square cm

Using the formula, we can calculate the length of the rectangle: Length = 160 cm² / 8 cm = 20 cm.

Now that we have the length and width of the rectangle, we can calculate the perimeter using the formula: Perimeter = 2 × (Length + Width).

Substituting the values, we get: Perimeter = 2 × (20 cm + 8 cm) = 2 × 28 cm = 56 cm.

Therefore, the length of the rectangle is 20 cm and the perimeter is 56 cm.

Answer

The length of the rectangle is 20 cm and the perimeter is 56 cm.
