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.
If sides of rectangle A to rectangle B has ratio 4 to 5. What would the perimeter of rectangle A if the rectangle B has a perimeter of 100 What about area of Rectangle A if the area of rectangle B is?
The perimeter of rectangle A would then be 80 because 80 to 100 is 4 to 5 simplified and the area of triangle A would depend on the sides and area of rectangle B which have not been given.
How do you measure triangle?
It depends on what you wish to measure: the lengths of sides, the angles, the area, the perimeter.
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.

Formula of a rectangle?
There is no formula for a rectangle. There are formula for calculating its area, perimeter or length of diagonals from its sides, or it is possible to calculate the length of one pair of sides given the other sides and the area or perimeter, or the two lots of sides given area and perimeter and so on.
A square and a triangle have an equal perimeters with the length of three sides of the triangle being 6.2 cm 8.3 cm and 9.5 cm so what is the area of the square?
Area of the square if 36 cm2ExplanationSince a square has 4 sides of equal length, we solve this problem by finding the perimeter of the triangle and dividing that number by 4.We are given the lengths of the 3 sides so the perimeter is their sum. Sine the perimeter of the triangle is 24, we know the each side of the square is length 6.The area is 62 or 36
If sides of rectangle A to rectangle B has ratio 4 to 5. What would the perimeter of rectangle A if the rectangle B has a perimeter of 100 What about area of Rectangle A if the area of rectangle B is?
The perimeter of rectangle A would then be 80 because 80 to 100 is 4 to 5 simplified and the area of triangle A would depend on the sides and area of rectangle B which have not been given.
What is the relation between perimeter and triangle area?
If you double (2 times) the perimeter the area will will be 4 times larger. Therefore the area is proportional to the square of the perimeter or the perimeter is proportional to the square root of area. The relationship as shown above applies only to triangles with similar proportions, that is when you scale up or down any triangle of fixed proportions. Other than that requirement, there is no relationship between perimeter and area of any shape of triangle except that it can be stated that the area will be maximum when the sides are of equal length (sides = 1/3 of perimeter).
How do l work out the area of a the perimeter of a triangle?
add up the length of all the sides

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 a triangle given only the perimeter?
It is possible depending on what type of triangle it is. For instance if it was an equilateral triangle then all sides would be equal and then by means of Pythagoras' theorem you could work out the height of the triangle and using the formula: 1/2*base*height = area
What is the contribution of Heron in mathematics?
he gave out the area of a triangle when sides are given Area of triangle = square root of ( s(s-a)(s-b)(s-c)), where s is the semi perimeter ie s= (a+b+c)/2
