What is the area and perimeter of triangle?
to find the area of a triangle you divide the base of the triangle by two and multiply your answer by the height .so your formula would be 1/2b times h to find the perimeter of a triangle u simply just add the sides.
How do you calculate a side of an equilateral triangle?
Find out what 1 side is and multiply by 3 to find perimeter
How do you find Ares and perimeter on a tringle?
-- Area of a triangle = 1/2 of (length of the base times height) -- Perimeter of a triangle = (length of one side) + (length of another side) + (length of last side)
What is the formula of a triangle in perimeter?
Perimeter of a triangle = (length of side #1) + (length of side #2) + (length of side #3)
What is the area and perimeter of a triangle 19cm x 21 cm?
To find the area of a triangle, you need the length of the base and the height. If the triangle has a base of 19 cm and a height of 21 cm, the area would be (1/2) * base * height = (1/2) * 19 cm * 21 cm = 199.5 cm^2. To find the perimeter of a triangle, you need to add the lengths of all three sides. Without knowing the lengths of the other sides, the perimeter cannot be determined.

What is the ratio of the length of a side of an equilateral triangle to its perimeter?
Length of a side of an equilateral triangle : Perimeter = 1 : 3 For example, if the length of the sides of an equilateral triangle were 5cm each, then perimeter would be three times that much - 15cm. 5 : 15 is the same as 1 : 3 when simplified. Length of a side of an equilateral triangle : Perimeter = 1 : 3 For example, if the length of the sides of an equilateral triangle were 5cm each, then perimeter would be three times that much - 15cm. 5 : 15 is the same as 1 : 3 when simplified.
How do you find the area of a triangle by Heron's formula?
