Question

Прямоугольный участок длина которого равна 10 целых 1/8 м а ширина составляет 2/3 ДЛИНЫ, ОБНЕСЕН ЗАБОРОМ ВЫСОТОЙ 1,6 М . НАЙТИ ПЛОЩАДЬ ЗАБОРА.

Answer 1

1) 10 1/8*2/3=81/8*2/3=27/4=6 3/4 м - ширина забора
2) 2*(10 1/8+6 3/4)=2*(81/8+27/4)=2*(81+54)/8=135/4=33,75 м - периметр забора
3) 33,75*1,6=54 м² - площадь

Answer 2

Calculation of the Fence Area

To find the area of the fence, we need to calculate the perimeter of the rectangular plot and then multiply it by the height of the fence.

Given: - Length of the rectangular plot = 10 1/8 m - Width of the rectangular plot = 2/3 * Length - Height of the fence = 1.6 m

Calculation Steps:

1. Convert the length of the rectangular plot to a mixed fraction: - 10 1/8 m = 81/8 m

2. Calculate the width of the rectangular plot: - Width = 2/3 * Length - Width = 2/3 * 81/8 m

3. Convert the width to a mixed fraction: - Width = 2/3 * 81/8 m = 162/24 m = 6 3/4 m

4. Calculate the perimeter of the rectangular plot: - Perimeter = 2 * (Length + Width) - Perimeter = 2 * (81/8 m + 6 3/4 m)

5. Convert the perimeter to a mixed fraction: - Perimeter = 2 * (81/8 m + 6 3/4 m) = 2 * (81/8 m + 27/4 m) = 2 * (162/16 m + 54/8 m) = 2 * (324/32 m + 108/16 m) = 2 * (432/32 m) = 27 m

6. Calculate the area of the fence: - Area = Perimeter * Height - Area = 27 m * 1.6 m

7. Calculate the final result: - Area = 27 m * 1.6 m = 43.2 square meters

Therefore, the area of the fence is 43.2 square meters.
