If we draw a semicircle below a triangle, we get the composite shape: The area of such a composite figure will be calculated by adding the area of the triangle and the area of the semicircle. Area of the a composite figure =(12×b×h)×(12+πr2) where r is the radius of the ...
Step 1:We can find the area of a triangle when an angle and two sides adjacent to the angle are given. Identify an angle and its two adjacent sides whose measurements are given. Step 2:Use the formula for the area of a triangle to compute the area. ...

trapezoid is rearranged as a triangle. Then the triangle obtained has the base (a + b) and height h. By applying the area of a triangle formula, the area of the trapezoid (or triangle) = ½ (a + b) h. For more information, you can refer toHow to Derive Area of Trapezoid ...
The surface area formula for a triangular prism is2 * (height x base / 2) + length x width1+ length x width2+ length x base, as seen in the figure below: A triangular prism is a stack of triangles, so the usually triangle solving rules apply when calculating the area of the bases...
