Question

Длина прямоугольного участка 720м,а ширина на 80м меньше.вфчислите площадь участка и выразите ее в гектарах

Answer 1

1) 720-80=640 м ширина
2) 720*640=460 800 кв.м площадь
460 800 кв м =46,8 га
1 га= 10 000 кв. м

Answer 2

Calculation of the Area of the Rectangular Plot

To calculate the area of a rectangular plot, we need to multiply its length by its width. In this case, the length of the plot is given as 720 meters, and the width is 80 meters less than the length.

Let's calculate the width of the plot first. Since the width is 80 meters less than the length, we can subtract 80 from the length to find the width:

Width = Length - 80 Width = 720 - 80 Width = 640 meters

Now that we have the length and width of the plot, we can calculate the area:

Area = Length * Width Area = 720 * 640 Area = 460,800 square meters

Conversion to Hectares

To express the area in hectares, we need to convert square meters to hectares. One hectare is equal to 10,000 square meters.

Let's perform the conversion:

Area in Hectares = Area in Square Meters / 10,000 Area in Hectares = 460,800 / 10,000 Area in Hectares = 46.08 hectares

Therefore, the area of the rectangular plot is 46.08 hectares.

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