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.
Find out what 1 side is and multiply by 3 to find perimeter
-- 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)
Perimeter of a triangle = (length of side #1) + (length of side #2) + (length of side #3)
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.
the ratio of the perimeter of triangle ABC to the perimeter of triangle JKL is 2:1. what is the perimeter of triangle JKL?
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.
Find out what 1 side is and multiply by 3 to find perimeter
the medial triangle is 1/2 the perimeter of the original triangle and has 1/4 the area of the original triangle
Area:A=1/2bhA=Area b=Base h=HeightPerimeter:P=a+b+cP=Perimeter a,b,c=side lengths of the triangle
-- 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)
Perimeter of a triangle = (length of side #1) + (length of side #2) + (length of side #3)
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.

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.
For finding the area of triangle with the help of Heron's formula: [s(s-a)(s-b)(s-c)]1/2 where a,b,c are sides of the triangle and s=1/2 of perimeter of the triangle
If you know the lengths of 2 sides and the included angle then use: Area of a triangle = 1/2*a*b*sinC
It is: 3*1 = 3 inches
