It is known that the perimeter of the parallelogram is 60cm, and the heights of the two adjacent sides are 8cm and 9cm respectively. The area of the parallelogram is calculated Try to be more detailed. I'm afraid I can't understand it, I have the wrong number. It's 68cm

It is known that the perimeter of the parallelogram is 60cm, and the heights of the two adjacent sides are 8cm and 9cm respectively. The area of the parallelogram is calculated Try to be more detailed. I'm afraid I can't understand it, I have the wrong number. It's 68cm

68/2=34 34*（8+9）=578 578/2=289
8 * 9 is absolute bullshit

It is known that the area of the parallelogram is 144cm2, and the heights of the two adjacent sides are 8cm and 9cm respectively, then the perimeter of the parallelogram is______ cm．

∵ the area of a parallelogram is equal to the side length × height, when the side height is 8cm, the side length is equal to 144 △ 8 = 18; when the side height is 9cm, the side length is equal to 144 △ 9 = 16. The perimeter of a parallelogram is 2 (18 + 16) = 68cm

Given the area of a parallelogram, how to find its perimeter

Given the area s of a parallelogram, the perimeter C of the parallelogram cannot be determined!
But there is a range: 4 √ s ≤ C ＜ + ∞
Happy Spring Festival!

The two adjacent sides of a parallelogram are 4cm and 6cm respectively. The distance between a group of opposite sides is 4.5cm. The area of this parallelogram is______ Square centimeter

4 × 4.5 = 18 (square centimeter); answer: the area of this parallelogram is 18 square centimeter

The length of two adjacent sides of a parallelogram is 4cm and 5cm respectively, and the angle between them is 30 degrees. The area of the parallelogram is

Height through the vertex of a parallelogram
Then the height of parallelogram is 4 * sin30 ° = 2cm
The area of a parallelogram is 5 * 2 = 10 (square centimeter)

The lengths of the two adjacent sides of a parallelogram are 4cm and 5cm respectively. The angle between them is 60 degrees. The area of the parallelogram is (added below)
A、10cm^2 B、10√3cm^2 C、5cm^2 D、5√3cm^2

Make a high road
According to trigonometric function, because the included angle is 60 degrees, so
The distance between the vertical foot and the left vertex is 2cm
The height is 2 √ 3cm
Thus, the area is 10 √ 3cm
So choose B

The area of a parallelogram is equal to that of a triangle. It is known that the bottom of a triangle is 2.4cm and the height is 4.5cm,
The bottom of the parallelogram is 2.7cm and the height is () cm

The area of a parallelogram is equal to that of a triangle. It is known that the bottom of a triangle is 2.4cm and the height is 4.5cm,
The bottom of the parallelogram is 2.7cm and the height is (2) cm

The bottom is 2.5cm, the height is 1.4 times of the bottom. How to find the area of parallelogram

So notice 2.5 * 1.4 = 3.5cm, the area of parallelogram is base times height, so its area is 2.5 * 3.5 = 8.75cm2

The bottom of a parallelogram is 18cm, the height is 8cm, and its area is___ What is the area of a triangle with the same base and height as it___ ．

18 × 8 = 144 (square centimeter) 144 △ 2 = 72 (square centimeter) answer: the area of this parallelogram is 144 square centimeter, and the area of the triangle with the same base and height is 72 square centimeter; so the answer is: 144cm2, 72cm2

The height of a triangle is 4cm. The area of a parallelogram is equal to the area of the triangle, and the bottom is equal. How many cm is the height of the parallelogram

Triangle area formula = (base x height) / 2 parallelogram area = base x height utilization area is equal, assuming that the base of the triangle is B, parallelogram height is a, then 1 / 2x4b = AXB, both sides of B are deleted, then a = 2, that is, the height of the quadrilateral is 2
