Question

Периметр сквера 660 м,его ширина на 40 м меньше длины.Найти площадь сквера.

Answer 1

660-80=580 м

580:4=145 м ширина

145+40=185 длина

145*185=26825 м кв

Problem Analysis

We are given that the perimeter of a square is 660 m, and its width is 40 m less than its length. We need to find the area of the square.

Solution

Let's assume the length of the square is L. According to the problem, the width is 40 m less than the length, so the width would be L - 40.

The perimeter of a square is given by the formula: Perimeter = 4 * side length.

In this case, the perimeter is given as 660 m, so we can write the equation as:

660 = 4 * (L + L - 40)

Simplifying the equation:

660 = 4 * (2L - 40)

Dividing both sides by 4:

165 = 2L - 40

Adding 40 to both sides:

205 = 2L

Dividing both sides by 2:

L = 102.5

Now that we have the length of the square, we can calculate the width:

Width = L - 40 = 102.5 - 40 = 62.5

The area of a square is given by the formula: Area = side length * side length.

So, the area of the square is:

Area = L * L = 102.5 * 102.5 = 10506.25 square meters

Therefore, the area of the square is 10506.25 square meters.

Answer

The area of the square is 10506.25 square meters.
