Formula for Area of A Triangle: 1/2 b x h (1/2 the base times the height).
The answer will be written in the name of the units squared.
Example: A triangle has a base of 10 inches and a height of 3 inches.
base: 10in height: 3in So, 1/2 b x h: 5 x 3= 15 inches squared (Can also be written as 15 inches with a small exponent two.)
The base is 13 units and the height is 6 units so use these dimensions to determine the 3rd side of the triangle.
That for any right angle triangle the length of its hypotenuse when squared is equal to the of length of the base when squared plus the length of the height when squared:- a2+b2 = c2 where a and b are the base and the height of the triangle and c is its hypotenuse.
well first off to get area in a triangle, you must multiply base X height so..... 25 X 12 = 300 sincerely the math armies' 325th platoon skull-plus
Pythagoras' theorem states that in a right angle triangle the lenght of the hypotenuse when squared is equal to the height squared plus the base squared. a2+b2 = c2 whereas a = height, b = base and c = hypotenuse
In a right angle triangle the square of the hypotenuse is equal to height squared plus base squared
The base is 13 units and the height is 6 units so use these dimensions to determine the 3rd side of the triangle.
Take the base and add 5.
The square of the length of the base plus the square of the length of the height will equal the square of the length of the hypotenuse of your right triangle, per Pythagoras. Square the hypotenuse, subtract the square of the height, and then find the positive square root of that and you'll have the base of your right triangle.

You probably know that the area of any triangle is (1/2) x (base) x (height).Take that formula, substitute (2x+3) in the place where it says "base", andsubstitute (3x-1) in the place where it says "height". Then do the multiplication,and you'll have a tidy expression for the area of your triangle.Of course, it'll still have an "x" in it, as well as an "x2", but you should expect that.If the base and the height both depend on the value of 'x', then naturally the areamust also depend on the value of 'x'.
That for any right angle triangle the length of its hypotenuse when squared is equal to the of length of the base when squared plus the length of the height when squared:- a2+b2 = c2 where a and b are the base and the height of the triangle and c is its hypotenuse.

The surface are of a right prism is equal to twice the area of its base plus the perimeter of the base multiplied with the height of the prism. The volume can be determined by multiplying the Area of the base by the height of the prism.
In a right angle triangle the square of the hypotenuse is equal to height squared plus base squared
For circle area: pi times radius squared. For circle circumference: 2 times pi times radius, for Square area: take the length of one side (doesn't matter which one because they are all equal) and square the number. For parallelogram area: take the base (bottom) and times it by the height (usually going up the middle.) For triangle area: take half of the base or height and times it by the whole base or height. For trapezoid area: the equation is half ( a side plus b side) times height. for rectangle area: width times height.
Area = base * height = 5*(4a + b) m2 = (20a + 5b) m2
