It can have any area greater than 0 cm2 and less than or equal to 81(3-√8) ≈ 13.897 cm2.
Without further information that provides the length of (at least) one side it is impossible to say which of these areas the triangle has.
For example:
base = 9 cm, hypotenuse = 9 cm
⇒ height = 18 - 9 - 9 cm = 0 cm
⇒ area = 9x0/2 = 0 cm2
This triangle does not actually exist and represents the minimum of the area.
base = 6 cm, hypotenuse = 7.5 cm
⇒ height = 18 - 6 - 7.5 cm = 4.5 cm
⇒ area = 6x4.5/2 = 12.5 cm2
Note that base2 + height2 = 36 + 20.25 = 56.25 = 7.52 = hypotenuse2 and so this is a right angle triangle.
base = 9(2-√2) cm ≈ 5.272 cm, hypotenuse = 18(√2 -1) cm ≈ 7.456 cm
⇒ height = 18 - 9(2-√2) - 18(√2 -1) cm = 9(2-√2) cm ≈ 5.272 cm
⇒ area = 9(2-√2) x 9(2-√2)/2 = 81(3-√8) cm2 ≈ 13.897 cm2
This triangle is a right angle triangle (check out Pythagoras on the lengths) and is the right angle triangle of largest area with perimeter 18 cm.
It is: perimeter minus hypotenus+base = height Area = 0.5*base*height
Using Pythagoras' theorem and the quadratic equation formula the sides of the triangle work out as 6.25 cm and 15 cm. Therefore the perimeter of the right angle triangle is: 6.25+15+16.25 = 37.5 cm
If you know the lengths of 2 sides and the included angle then use: Area of a triangle = 1/2*a*b*sinC
There are different formula for: Height, Area, Perimeter, Angle, Length of Median Radius of inscribed circle Perimeter of inscribed circle Area of inscribed circle etc.
It is the perimeter of a triangle times the length of the prism (in square units).
A right angle triangle fits the dimensions given
It is: perimeter minus hypotenus+base = height Area = 0.5*base*height
how to find the perimeter of a right angled triangle using the area
Using Pythagoras' theorem and the quadratic equation formula the sides of the triangle work out as 6.25 cm and 15 cm. Therefore the perimeter of the right angle triangle is: 6.25+15+16.25 = 37.5 cm
Area of a right angle triangle is: 0.5*base*height
Perimeter: 8+15+17 = 40 cm Area: 0.5*8*15 = 60 square cm
The perimeter of a triangle does not provide sufficient information to calculate its area.
If you know the lengths of 2 sides and the included angle then use: Area of a triangle = 1/2*a*b*sinC
area=(1/2)*base*height
There are different formula for: Height, Area, Perimeter, Angle, Length of Median Radius of inscribed circle Perimeter of inscribed circle Area of inscribed circle etc.
It is the perimeter of a triangle times the length of the prism (in square units).
There is no right triangle on the right! (Ignore the length of the hypotenuse of a right triangle.) if you have the length of the two legs (base and the upright side): (base x upright) ÷ 2 = area of the right angle triangle.
