Right Angled Triangle Formula What is the area of a right triangle with hypotenuse 5 cm and angle 45°? the area is 6.25. we get this answer by applying the formula area = c² × sin (α) × cos (α) 2 with c = 5 and α = 45°. the math theorem used to derive this formula is called the law of sines. Example 2: calculate the height of the right triangle, whose base length is 60 m and area is 420 m 2. solution: given: base = 60 m. area = 420 m 2. the formula for the area of a right angle triangle is a = (½)×b×h square units. now, substitute the values in the formula. 420 = (½)×60×h.

How To Find Area Of Triangle Right Angle Haiper Learn how to find the area of a right angled triangle using the formula a = 1 2bh, where b is the base length and h is the height. see examples with given and missing lengths, angles and hypotenuse, and practice with a worksheet. Learn how to find the area of a right triangle using base and height or hypotenuse. see the formula, derivation and examples with solutions and worksheets. This means the area of each right triangle is exactly half the area of the rectangle. the general formula to find the area of any triangle is: area of a triangle = base × height 2 area of a triangle = 2 base × height. this can also be written as the following formula: a = 1 2bha = 21 bh. where bb is the base length and hh is the height of the. All that you need are the lengths of the base and the height. in a right triangle, the base and the height are the two sides that form the right angle. since multiplying these two values together would give the area of the corresponding rectangle, and the triangle is half of that, the formula is: area = ½ × base × height.
