How do you find the area of a triangle when given 3 angles and the perimeter?

If you know the lengths of 2 sides and the included angle then use:
Area of a triangle = 1/2*a*b*sinC

How do you find the perimeter of a triangle if you know the area?
You cannot. For a given area, an equilateral triangle will have the smallest perimeter but that perimeter can be increased - without limit - without increasing the area.
How do you measure triangle?
It depends on what you wish to measure: the lengths of sides, the angles, the area, the perimeter.
How do you work out the value of a triangle?
A triangle does not have any particular value. There are the magnitudes of its size, its angles, its area, its perimeter etc, but no single VALUE.
Sides of traingle giving equal permeter and area?
I am assuming that "traingle" is meant to be triangle and "permeter" is meant to be perimeter.The area of a triangle cannot be equal to its perimeter because the area is a measure in 2-dimensional space whereas a perimeter is a 1-dimensional measure. So their dimensions will always be different.Furthermore, the area of a triangle is not determined by its perimeter. The area of a triangle can be changed - without affecting its perimeter - simply by changing the angles.
If the area of triangle B is 64 times greater than the area of triangle A how much greater is the perimeter of triangle B?
IF triangles 'A' and 'B' are similar (they both have the same angles),then the perimeter of 'B' is 8 times the perimeter of 'A'.If they're not similar, then the ratio of areas doesn't tell you the ratioof perimeters.
Can you find the area of a triangle when give the perimeter and 3 angles?
yes

What is the formala for a triangle?
There is not one, but several formulae for triangles - depending on whether you want to calculate the angles, the lengths of the sides, the perimeter, the area, etc., and depending on what information is already known.

What is the area of a triangle that has a perimeter of 37?
The perimeter of a triangle does not provide sufficient information to calculate its area.
Find the area of a triangle that has a perimeter of 21 inches?
I need to know more about the triangle, such as one or 2 of the angles, whether it is isosceles or equilateral, or whether the lengths share a certain ratio. For example, a triangle of sides 8,8 and 5 (perimeter of 21) will surely have a different area as compared to a triangle of sides 7,7 and 7 (perimeter of 21 as well)
How do you find the area of the right angle triangle given the base hypotenuse and perimeter?
It is: perimeter minus hypotenus+base = height Area = 0.5*base*height
What shape has an area of 6cm but perimeter of 12cm?
A right angle triangle fits the dimensions given
What is the perimeter and area of a triangle whose longest side is 162cm when two of its angles are 37.25 degrees and 48.4 degrees?
Using the sine rule in trigonometry the perimeter of the triangle is 381.83 cm and its area is 5956.67 square cm both rounded to two decimal places
