The area of a triangular wheat field is 1620 square meters. The length of its bottom is 36 meters. How high is the field?


A: the height of this land is 90 meters



There is a triangular wheat field with an area of 12000 square meters. The length of one side of the triangular field is 200 meters, and there is a water pipe at the top opposite to this side. How many meters is the shortest way from this side to this water pipe?


The shortest way from this side to this water pipe is the height of this side
12000 × 2 △ 200 = 120 (m)
A: at least 120 meters



The area of a triangular wheat field is 1620 square meters. The length of its bottom is 36 meters. How high is the field?


A: the height of this land is 90 meters



In the triangle ABC, the length of three sides is a = 2, B = 3, C = 4 respectively. Find the area of the triangle ABC


If a = 2, B = 3, C = 4
Using cosine theorem cosa = (b ^ 2 + C ^ 2-A ^ 2) / 2BC = 7 / 8
sinA= √(1-cos^2A)=(√15)/8
Area s = 1 / 2 · BC · Sina = (3 √ 15) / 4



One side of a triangle is 18cm. To make its area not larger than the area of a square whose side length is 5cm, the value range of the height of the known side of the triangle is obtained


1/2*h*18



The length of one side of a triangle is 18cm. To make its area not greater than the area of a square 5cm in length, the value range of the height of the known side of the triangle is obtained


High: H
18h÷2≤5x5
9h≤25
h≤25/9
The value range of high is 0



The hypotenuse of isosceles triangle is 5cm, and the base is 6cm
I haven't learned the root sign yet. I only learned Pythagorean theorem and only used Pythagorean theorem to solve it


The middle line of the bottom of the isosceles triangle is the height of the bottom
According to the Pythagorean theorem, if the hypotenuse is 5 and a right angle side is 3, then the height of the other straight angle side, that is, the bottom side, is 4
Therefore, the area of triangle: = 1 / 2 * 6 * 4 = 12 cm2



If the two sides of a triangle are 6 and 8 long, and the angle between the two sides is 60 degrees, the area of the triangle is


Make a vertical line from either end of the two sides to the other side, and the included angle is 60. If you make a vertical line from the end of 6, then the included angle is 60, which means that the vertical line is 3 root sign 3, and the area is 3 root sign 3 times 8 divided by 2 = 12 root sign 3



The height of a parallelogram is 4.3dm, the bottom is twice as high, and its area is () DM2


Bottom
4.3 × 2 = 8.6 (decimeter)
the measure of area
8.6 × 4.3 = 36.98 (square decimeter)



The area of a parallelogram is 128 square decimeters, the bottom is twice as high, and the bottom is 128 square decimeters______ Decimeter, height is______ Decimeter


Let the height be x decimeter, the bottom be 2x decimeter, 2x × x = 128 & nbsp; X × x = 128 △ 2 & nbsp; X × x = 64 and 8 × 8 = 64; so x = 8, 2x = 2 × 8 = 16 (decimeter) answer: the bottom is 16 decimeter, the height is 8 decimeter; so the answer is: 16, 8
