Let the following side after the angle be x:-
If: 0.5*8.2*x*sin(43.84) = 18.18
Then: x = (2*18.18)/8.2*sin(43.84) = 6.4
Using the cosine rule the 3rd side works out as 5.7
Perimeter of scalene triangle: 8.2+6.4+5.7 = 20.3 cm
Area = 0.5*7.52*sin(60 degrees) = 24.357 square cm rounded to 3 dp.
You can draw any shape you want with a perimeter of 20. For a square, make each side 5. For a triangle, 62/3 , etc.
Answer: absolutely not! Answer: No. For starters, the area uses units of area (for example, square centimeters), while the perimeter uses units of length (For example, centimeters).
180
A square with an area of 400 square units has a perimeter of 80 units.
Using the sine rule in trigonometry its area is 192.885 square cm and its perimeter is 65.379 cm both rounded to three decimal places.
The perimeter of the square is 96.
Using the sine rule a/A = b/B = c/B the perimeter of the triangle works out as 382.02 cm with an area of 5965.8 square cm rounded to one decimal place.
Area of equilateral triangle: 0.5*12*12*sin(60 degrees) = 187 square cm
Pythagoras discovered that a scalene triangle is in fact a square
Yes.
Suppose the side of the square is x cm.Then its perimeter is 4x cm.The perimeter of the square is 3 cm more than that of the triangleso the perimeter of the triangle is 4x - 3 cm.Also, if the side of the square is x cm, the side of the triangle must be x + 112 cm.Then its perimeter must be 3*(x + 112) = 3x = 336 cm.Equating the two expressions for the perimeter of the triangle,4x - 3 = 3x + 336therefore x = 339 cm.The square has sides of 339 cm and a perimeter of 1356 cm.The triangle has sides of 451 cm and a perimeter of 1353 cm.
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
Perimeter of which geometry (square, circle, rectangle, triangle, ...)
Area of equilateral triangle: 0.5*8*8*sin(60 degrees) = 27.7 square inches rounded
Square and scalene triangle are shapes.
Square is 360 and so is a circle A triangle is 180 degrees half a triangle or quarter of a square is 90 degrees
