WebStep 1: Calculate "s" (half of the triangles perimeter): s = a+b+c 2 Step 2: Then calculate the Area: A = √s (s−a) (s−b) (s−c) Example: What is the area of a triangle where every side is 5 long? Step 1: s = 5+5+5 2 = 7.5 Step 2: A = √ (7.5 × 2.5 × 2.5 × 2.5) = √ (117.1875) = 10.825... Try it yourself: Hero of Alexandria WebThe formula for the perimeter of a rectangle is, P = length + breadth + length + breadth. Or, P = 2 (length + breadth) Find the perimeter of a rectangle if its length is 6 cm and breadth is 4 cm. We know that, perimeter of a rectangle = 2 (Length + Breadth) units. Substituting the given values, we get P = 2 (6+4) = 2 (10) = 20

WebJul 1, 2024 · The answer is 84. It comes from the right triangle ( 12, 35, 37). You want the maximum of 12 + a + b where a and b are such that 12 2 + a 2 = b 2. This is equivalent to ( b − a) ( b + a) = 144. Making the list of all possible ways of expressing 144 as the product of two numbers both of which are even, you will find that the list is rather short. WebThe Right-Angle formulas refer to those formulas that are associated with right-angled triangles and assist in calculating the area, perimeter etc. of the triangle. The Formulas … WebFeb 2, 2024 · How do I find the area of a right triangle given sides? The method depends on which sides you're given: If you know the two legs, then use the formula area = a × b / 2, where a, and b are the legs. If you know one leg a and the hypotenuse c, use the formula: area = a × √ (c² - a²) / 2. how often do rattlesnakes shed skin
