Web2. If the area of an equilateral triangle is 163 ft2, find the side of the triangle. Solution: Area = 163 ft2. Let the side of an equilateral triangle be a ft. 3a24=163. a2=64 . a=8 ft. Side of the triangle = 8 ft. 3. Find the area of an equilateral triangle whose height is 53 units. Solution: Height = h = 3a2. 53= 3a2. a=10 unit WebJust use this two step process: Step 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:

WebWith only two sides of the triangle known (and that the line perpendicular to AB, and intersecting C, forms divides ABC into two right triangles), we still don't have enough information to determine height (h). See Americo's … Web1 Answer. Besides the solution you stated using Heron's formula, you can use the Law of Cosines to find one of the angles. The height is then easily obtained by dropping the appropriate perpendicular and using the definition of … WebMar 18, 2013 · Any triangle has three altitudes and three bases. You can use any one altitude-base pair to find the area of the triangle, via the formula A = 1 2 b h. In each of the diagrams above, the triangle ABC is the same. The green line is the altitude, the “height”, and the side with the red perpendicular square on it is the “base.”. how to transform your life into a work of art
