Question

Помогите решить задачу чтоб было дано решение и ответ. Указание: Площадь опоры ботинка определите следующим образом. Поставьте ногу на лист клетчатой бумаги и обведите контур и обведите конторой той части подошвы, на которую опирается нога. Сосчитайте число полных квадратиков, попавших внутрь контура, и прибавьте к нему половину числа неполных квадратиков, через которые прошла линия контура. Полученное число умножьте на площадь одного квадратика( площадь квадратика на листе, взятом из школьной тетради, равна 1/4 см в квадрате) и найдите площадь подошвы. Кол-во полных клеток- 511 кол- во не полн.-94

Answer 1

To solve the problem and find the area of the shoe's sole, you need to follow these steps:

1. Place your foot on a sheet of grid paper. 2. Trace the outline of your foot, including the part of the sole that touches the ground. 3. Count the number of complete squares that are inside the traced outline. 4. Add half the number of squares that are partially covered by the outline. 5. Multiply the total number obtained by the area of one square on the grid paper.

Given that the number of complete squares is 511 and the number of partially covered squares is 94, we can proceed with the calculations.

Calculation:

1. Number of complete squares: 511 2. Number of partially covered squares: 94

To find the area of the shoe's sole, we need to calculate the total number of squares and multiply it by the area of one square on the grid paper.

The total number of squares is the sum of the complete squares and half the number of partially covered squares:

Total number of squares = Number of complete squares + (1/2) * Number of partially covered squares

Total number of squares = 511 + (1/2) * 94

Now, we need to multiply the total number of squares by the area of one square on the grid paper. The area of one square is given as 1/4 square cm.

Area of the shoe's sole = Total number of squares * Area of one square

Area of the shoe's sole = (511 + (1/2) * 94) * (1/4) square cm

Let's calculate the area:

Area of the shoe's sole = (511 + (1/2) * 94) * (1/4) square cm Area of the shoe's sole = (511 + 47) * (1/4) square cm Area of the shoe's sole = 558 * (1/4) square cm Area of the shoe's sole = 139.5 square cm

Therefore, the area of the shoe's sole is 139.5 square cm.

Please note that the calculations provided above are based on the given information and assumptions.
