What is the formula for perimeter and area of a triangle?
Perimeter, Area, and Volume
| Table 1 . Perimeter Formulas | ||
|---|---|---|
| Shape | Formula | Variables |
| Triangle | a+b+c | a,b , and c are the side lengths. |
| Right Triangle, with legs a and b (see Pythagorean Theorem ) | P=a+b+√a2+b2 | a and b are the lengths of the two legs of the triangle |
| Circle | P=C=2πr=πd | r is the radius and d is the diameter. |
What is the area of the triangle?
The area A of a triangle is given by the formula A=12bh where b is the base and h is the height of the triangle.
What is the perimeter of a triangle?
Example 2: Find the perimeter of a triangle whose each side is 10 cm. Solution: Since all three sides are equal in length, the triangle is an equilateral triangle. Perimeter = 30 cm….Read More:

What is the area of the perimeter?
The area for a 2-dimensional shape is the space enclosed within the perimeter of the given shape. To calculate the area for different shapes, use different formulas based on the number of sides and other characteristics such as angles between the sides.
How do you find the perimeter and area?
Assuming the room is square or rectangular, you would measure the length and width. Multiply the length by the width to get the area, and add twice the length to twice the width to get the perimeter.
How do you find the third side and perimeter of a triangle given two sides?
Method 1 of 3: Finding the Perimeter When Three Side Lengths are Known. Remember the formula for finding the perimeter of a triangle. For a triangle with sides a, b and c, the perimeter P is defined as: P = a + b + c.
How to calculate the perimeter of a triangle?
Thus, the perimeter of an equilateral triangle is 3 times the length of each side. Area of a triangle Area of a two-dimensional shape is the space occupied by the shape. This area can be found by dividing the shape into unit squares and determining the number of unit squares in the shape as each unit square occupies one square unit space.
How do you find the perimeter of a polygon?
To find the perimeter of a polygon, add together the lengths of each side, . can only be used for equilateral triangles, not all triangles. And can only be used for isosceles triangles. What is the area of this triangle?
How to find the area of a triangle given three sides?
The area of the triangle is the region enclosed by its perimeter or the three sides of the triangle. What is the area when two sides of a triangle and included angle are given? The area will be equal to half times of the product of two given sides and sine of the included angle. How to find the area of a triangle given three sides?
What do you need to know about area and perimeter?
Learn area of different shapes here. Area and Perimeter is an important topic in Mathematics, which is used in everyday life. This is applicable for any shape and size whether it is regular or irregular. You must have learned about different shapes such as triangle, square, rectangle, circle, sphere, etc.
