Answer 1

210*14=15
130*15=1950грн

Answer 2

210:14=15 м длина
(15+14)*2=29*2=58 м периметр
58*130=7540 грн потратили

Answer 3

Calculation of the Cost of the Net for the Sports Field

To calculate the cost of the net for the rectangular sports field, we need to know the perimeter of the field and the price of the net per meter.

Given: - Width of the field = 14 meters - Area of the field = 210 square meters - Price of the net per meter = 130 UAH

To find the perimeter of the field, we can use the formula: perimeter = 2 * (length + width).

Since we only have the width of the field, we need to find the length. We can use the formula: area = length * width.

Let's calculate the length of the field first:

area = length * width 210 = length * 14 length = 210 / 14 length = 15 meters

Now that we have the length and width of the field, we can calculate the perimeter:

perimeter = 2 * (length + width) perimeter = 2 * (15 + 14) perimeter = 2 * 29 perimeter = 58 meters

The cost of the net for the perimeter of the field can be calculated by multiplying the perimeter by the price per meter:

cost = perimeter * price per meter cost = 58 * 130 cost = 7540 UAH

Therefore, the cost of the net for the rectangular sports field is 7540 UAH.
