Using the cosine formula the angle between lengths 8 and 12 is 55.77113367 degrees.
Using the sine formula the area of the triangle is 39.68626966 or about 40 square units.

The area of a triangle is (1/2) x base x height. The height is perpendicular to the base. In this case, you can take the 10 cm as the base, and calculate the height with Pythagoras' formula. If you split the base in half now you have two 5-12-13 right triangles, so the height is 12 cm and the area is (1/2)*(10cm)*(12cm) = 60 cm2
The area of triangle is : 60.0
Yes.
(12*12)/2 = 72
Two sides of a triangle are not enough to determine its shape and so it is impossible to find its area.
The area of triangle is : 60.0
Use Pythagoras to find the perpendicular height of the triangle: 132-52 = 144 and the square root of this is the height of the triangle which is 12 cm Area = 1/2*12*10 = 60 square cm
What is 12 in ? And what is 16 in ? ? Are they the lengths of two sides of the triangle ? Are they the length of one side and the height of the triangle ? The area of any triangle is 1/2 of the product of (length of its base) x (its height).
About 62 Feet squared
Area = 0.5*5*12 = 30 square units
There is no such thing as a triangle with twelve sides.
