Question

Прямоугольный котлован длинной 17 м и шириной 15 м обнести оградой стоящей на 3 м от ямы. Найти длинну ограды.

Answer 1

1) 17+3=20(м) длина ограды
2) 15+3=18(м) ширина ограды
3) 20*2+18*2=76(м) длина ограды

Answer 2

Calculating the Length of the Fence

To find the length of the fence needed to enclose a rectangular pit with a length of 17m and a width of 15m, we can use the formula for the perimeter of a rectangle, which is given by the equation:

Perimeter = 2 * (length + width)

Applying the Formula

Using the given dimensions, we can calculate the length of the fence required:

Perimeter = 2 * (17 + 15)

Perimeter = 2 * 32

Perimeter = 64 meters

So, the length of the fence needed to enclose the rectangular pit is 64 meters.
