Answer 1

1.30х10=300
2.300метров х 2=600(м2)
ответ:600 кв.метров площадь учстков

Answer 2

Calculation of the Area and Perimeter

To find the area of the combined rectangular sections and the length of the surrounding fence, we need to consider the dimensions of the individual rectangular sections.

Given: - Two identical rectangular sections with dimensions 10m x 30m.

To find the area of the combined rectangular sections, we can add the areas of the two individual sections:

Area of one rectangular section = length x width = 10m x 30m = 300 square meters

Area of the combined rectangular sections = 2 x (Area of one rectangular section) = 2 x 300 square meters = 600 square meters

Therefore, the area of the combined rectangular sections is 600 square meters.

To find the length of the surrounding fence, we need to calculate the perimeter of the combined rectangular sections. Since the two rectangular sections are joined together, we only need to calculate the perimeter of three sides (top, bottom, and one side).

Perimeter of one rectangular section = 2 x (length + width) = 2 x (10m + 30m) = 2 x 40m = 80 meters

Perimeter of the combined rectangular sections = 2 x (Perimeter of one rectangular section) + length of the common side = 2 x 80 meters + 30 meters = 160 meters + 30 meters = 190 meters

Therefore, the length of the surrounding fence is 190 meters.

Please note that the above calculations assume that the two rectangular sections are joined along one of their sides. If they are joined along a different configuration, please provide more specific information for an accurate calculation.
