The ratio of the three sides of a triangle is 2:4:5. The longest side is 6cm longer than the shortest side. Find out the circumference of the triangle with the equation
Let the three sides be 2x, 4x, 5x,
5x-2x=6
X=2
Three sides 4 cm, 8 cm, 10 cm, circumference 22 cm
The circumference of the triangle is 9.6 decimeters, the two corners are 60 degrees, how many decimeters is the base of the equation to solve! Urgent, The bottom edge is set as X decimeter
If two angles of a triangle are 60 degrees, the third angle is also 60 degrees
Suppose that all three sides of a triangle are x decimeters
3x=9.6
x=3.2
The bottom is 3.2 decimeters
The circumference of a triangle is 18 / 7 decimeter, and the length of two sides is 1 / 6 respectively. What is the length of the other and side
Let the length of the other side be x decimeters
X+1/6+1/6=7/18、
X+1/3=7/18、
X=1/18

7.5x3 = 22.5 decimeter = 225 cm
An equilateral triangle has a circumference of 28.5 cm, a height of 6.4 cm, and an area of______ Square centimeter
28.5÷3×6.4÷2,
=9.5×6.4÷2,
=4 (square centimeter);
A: the area is 30.4 square centimeters,
Therefore, the answer is: 30.4
An equilateral triangle has a circumference of 18 decimeters and a height of 1.2 decimeters. What is its area
The base of an equilateral triangle: 18 △ 3 = 6 decimeters
Area: 6 × 1.2 △ 2 = 3.6 square decimeter

∵ this triangle is an equilateral triangle
The side length of an equilateral triangle is: 15 △ 3 = 5cm
The height is 6 cm
The area of equilateral triangle = base × height △ 2 = 5 × 6 △ 2 = 15 square centimeter
Answer
An equilateral triangle has a circumference of 24 decimeters and a height of 3. What is the area
It is calculated as follows: the three sides of an equilateral triangle are equal, and the perimeter is the sum of the three sides. Therefore, 24 △ 3 = 8, and the side length of the triangle is 8 decimeters. Because the area is equal to the base times the height divided by two, the area is equal to 8 * 3.5 △ 2 = 14 (DM 2)
