Question

Прямоугольный участок длина которого 10 целых одна восьмая метра , а ширина составляет две третьих длины., обнесён забором высотой одна целая шесть десятых. площадь забора?

Answer 1

10 целых одна восьмая метра=81/8 - длина участка

т.к. две третьих длины, то =81/10*2/3=27/4 - ширина участка

высотой одна целая шесть десятых=16/10 - высота забора

S(забора)=?

находим S забора по длине =81/8*16/10=81/5(м в квадрате)

находим S забора по ширине =27/4*16/10=54/5(м в квадрате)

S(забора)=2(S забора по длине)+2(S забора по ширине)=

=2*81/5+2*54/5= 54(м в квадрате)

   Ответ: S(забора)= 54 м в квадрате.

Answer 2

Calculation of Fence Area

To calculate the area of the fence, we need to find the length and width of the rectangular plot and the height of the fence.

Given: - Length of the rectangular plot: 10 whole units + 1/8 meter - Width of the rectangular plot: 2/3 of the length - Height of the fence: 1 whole unit + 6/10

Let's calculate the length, width, and height in meters first.

1. Length of the rectangular plot: - 10 whole units + 1/8 meter - Converting the whole units to meters: 10 * 1 = 10 meters - Converting 1/8 meter to meters: 1/8 * 1 = 1/8 meter - Adding the converted values: 10 meters + 1/8 meter = 10 1/8 meters

2. Width of the rectangular plot: - 2/3 of the length - Converting the length to a fraction: 10 1/8 = 81/8 meters - Calculating 2/3 of the length: (2/3) * (81/8) = 162/24 meters = 6 3/8 meters

3. Height of the fence: - 1 whole unit + 6/10 - Converting the whole unit to meters: 1 * 1 = 1 meter - Converting 6/10 to meters: 6/10 * 1 = 6/10 meter - Adding the converted values: 1 meter + 6/10 meter = 1 6/10 meters

Now that we have the length, width, and height of the fence in meters, we can calculate the area of the fence.

The area of the fence is given by the formula: Area = 2 * (Length + Width) * Height.

Substituting the values: - Length = 10 1/8 meters - Width = 6 3/8 meters - Height = 1 6/10 meters

Area = 2 * (10 1/8 + 6 3/8) * 1 6/10

Let's calculate the area:

Area = 2 * (10 1/8 + 6 3/8) * 1 6/10 = 2 * (81/8 + 51/8) * 16/10 = 2 * (132/8) * 16/10 = 2 * (33/2) * 8/5 = 2 * 33 * 8 / (2 * 5) = 264 / 5 = 52 4/5 square meters

Therefore, the area of the fence is 52 4/5 square meters.
