What is the formula of perimeter and triangle?
What is the formula of perimeter and triangle?
To calculate the perimeter of a triangle, add the length of its sides. For example, if a triangle has sides a, b, and c, then the perimeter of that triangle will be P = a + b + c.
What is the perimeter of a Sierpinski triangle?
Since the side of the inital triangle was divided into three equal line segments, the new side length of every side (old and new sides) is 1 3 the length of the initial side length. Thus, the perimeter is P1 = 3 × 4 × 1 3 = 12 × 1 3 = 4 units.
How many triangles are there in Sierpinski triangle?
three triangles
This leaves us with three triangles, each of which has dimensions exactly one-half the dimensions of the original triangle, and area exactly one-fourth of the original area.
What is the area formula?
2. The area of a simple, closed, planar curve is the amount of space inside….Perimeter, Area, and Volume.
| Table 2. Area Formulas | ||
|---|---|---|
| Shape | Formula | Variables |
| Square | A=s2 | s is the length of the side of the square. |
| Rectangle | A=LW | L and W are the lengths of the rectangle’s sides (length and width). |
| Triangle | A=12bh | b and h are the base and height |
Can the area and perimeter of a triangle be the same?
Its perimeter and area will be numerically equal. For example; consider the familiar 3-4-5 right triangle: P = 12, A = 6 so x = 12/6 = 2. So a triangle with sides 6, 8 and 10 will have the same numerical perimeter and area (24 units each).
Does a triangle with a fixed perimeter have a fixed area?
The triangle will have a fixed perimeter, but the area will vary. A common error is to assume that a triangle that has a fixed perimeter must also have a fixed area. This is definitely not the case as can be seen from the figure above. As you drag the orange point A, the triangle will maintain a fixed perimeter.
How do you find the perimeter of an equilateral triangle?
Since all the three sides of the triangle are of equal length, we can find the perimeter by multiplying the length of each side by 3. 20 + 20 + 20 = 3 × 20 = 60 cm. Thus, the perimeter of an equilateral triangle is 3 times the length of each side. Area of a triangle
How do you find the area of a rectangle?
That is, the area of a rectangle is the product of its length and width. A rectangle can be divided into two congruent triangles. So, the area of each triangle is half the area of the rectangle.
How do you find the area of a triangle?
A rectangle can be divided into two congruent triangles. So, the area of each triangle is half the area of the rectangle. That is 1 ⁄ 2 x l x w. Consider a scalene triangle △ABC. Note that, to write the area of a triangle as half the area of a rectangle, we need to have the height perpendicular to the base.
