Question

Прчмоугольный участок земли размером 130×60 м окопали рвом шириной 1 м , причем ров выкопали на участке. какова новая площадь участка?

Answer 1

Ширина участка уменьшилась на 1+1=2 метра и стала равна 58 м.
Длина уменьшилась тоже на 2 м и стала равна 128 м.

Sуч.=128*58=7424 м² -новая площадь участка

Answer 2

Calculating the New Area of the Land Plot

To calculate the new area of the land plot after the ditch was dug, we can use the formula:

New Area = Original Area - Area of Ditch

The original area of the land plot is 130m * 60m.

The ditch has a width of 1m and runs along the entire length of the plot.

Calculating the Area of the Ditch

The area of the ditch can be calculated using the formula:

Area of Ditch = Length of Ditch * Width of Ditch

In this case, the length of the ditch is the same as the length of the plot (130m), and the width of the ditch is 1m.

Calculating the New Area

Using the above information, we can calculate the new area of the land plot:

New Area = (130 * 60) - (130 * 1) = 7800 - 130 = 7670 square meters

Therefore, the new area of the land plot is 7670 square meters.
