The area of a triangular vegetable field is 30 square meters, and its height is 5 meters. How long is the bottom of this vegetable field? 30 × 2 △ 5 = 12m

The area of a triangular vegetable field is 30 square meters, and its height is 5 meters. How long is the bottom of this vegetable field? 30 × 2 △ 5 = 12m


Suppose the length of the bottom edge of this vegetable field is x, then according to the meaning of the title, it is 5x △ 2 = 30, x = 12, then the length of the bottom edge of this vegetable field is 12 meters



Parallelogram with equal base and height has larger area than triangle______ %.


The area ratio of a parallelogram with equal base and height to a triangle is: ah: 12Ah = 2:1; the area of a parallelogram with equal base and height is larger than that of a triangle: (2-1) △ 1 = 100%; so the answer is: 100



A triangle and a parallelogram are of equal base and height. The area of the parallelogram is 2
How many square centimeters is the area of this parallelogram


The area of a parallelogram is the base times the height, and the area of a triangle is the base times the height divided by 2
That is to say, a triangle with equal base and height is half the area of a parallelogram
2.6 square centimeter is the area of triangle, 5.2 is the area of parallelogram



What is the area ratio of a triangle and a parallelogram with equal base and height


Triangle area = bottom * height / 2
Area of parallelogram = bottom * height
Area ratio = 1:2



Around a round pool with a diameter of 10 meters, build a stone road with a width of 1 meter. What is the area of this stone road?


10 △ 2 = 5 (m) 5 + 1 = 6 (m) 3.14 × (62-52) = 3.14 × (36-25) = 3.14 × 11 = 34.54 (M2). A: the area of this stone road is 34.54 m2



A circular garden is 8 meters in diameter. There is a 1 meter wide path around the garden. What is the area of this path?


Just reduce the area of the big circle! The diameter is 8 meters, so the radius of the small circle is 4. The width of the small road is 1 meter, so the radius of the big circle is 5,
  3.14×5×5-3.14×4×4
=3.14×25-3.14×16
=3.14×(25-16)
=3.14×9
= 28.26 square meters



Does floor area include green space?
The floor area is calculated by the external horizontal area of the exterior wall (above the bottom plinth)
Is this definition correct?
Is there a great Xia who understands?


Basically, there is no special explanation
It can be considered according to the specific situation



What is the change of green space area? The topics are increasing area and decreasing area


Change = increase decrease



If there is an unknown number of households, and each household has an average area of 150 square meters, the green space area will account for 60% of the building area, and if there are 2 more


Real estate related formula (static investment payback period = [years with positive cumulative net cash flow - 1] + [absolute value of cumulative net cash flow of last year / net cash flow of current year] dynamic investment payback period = [years with positive cumulative net cash flow present value - 1] + [absolute value of cumulative net cash flow present value of last year / net cash flow of current year



Does building area include green area? Does 30% green area mean 30% of building area


The construction area does not include the green area. The green area 30% refers to 30% of the land area occupied by the project
