My father gave me something to answer and a. Area of a Trapezoid = A = 1 2 h (a + b) Where: A trapezoidal prism is a three-dimensional solid that is made up of two trapezoids on opposite faces which are joined by four rectangles called the lateral faces. Solution: The area of a trapezoid = (a + b) h; where a = 7, b = 9, h = 5. Hence, the area of a trapezoid is calculated by the following formula: Area = [ (AB + CD)/2] h A = [ (a + b)/2] h Where, AB and CD = parallel sides a = shorter base b = longer base Since the trapezoidal prism has a flat base, thus we can say that it has a total surface area and a curved surface area. where, This image is not<\/b> licensed under the Creative Commons license applied to text content and some other images posted to the wikiHow website. X The formula for the area of a trapezoid is (base 1 + base 2) / 2 x height, as seen in the figure below: The calculation essentially relies on the fact a trapezoid's area can be equated to that of a rectangle: (base 1 + base 2) / 2 is actually the width of a rectangle with an equivalent area. Meaning that if you know all of these dimensions, you'll be able to calculate the area of your right trapezoid directly. another interesting way to think about it. An acute trapezium has two adjoining acute angles on its longer base edge, while an obtuse trapezoid has one acute and one obtuse angle on each base. #S = 2*h/2 (a + b) + al + cl + bl + dl#, Simplify: Volume & Surface Area of a Trapezoidal Prism The length of the four rectangles will be the sum of the four sides of the trapezoid, the two bases, and the other two sides. Answer: The length of the other base of the given trapezoid = 10 units. area of the trapezoid should be in between Now, what would happen if Example: Find the area of a trapezoid in which the bases (parallel sides) are given as 6 and 14 units respectively, and the non-parallel sides (legs) are given as, 5 units each. What is the Surface Area of Trapezoidal Prism? Using the Pythagoras theorem in the right-angled triangles, we can calculate the height. The surface area S = 2 ABase + Lateral Surface Area Atrapezoid = ABase = h 2 (a +b) L = Lateral Surface Area = the sum of the areas of each surface around the Base. We know that the area of a trapezoid whose bases are 'a' and 'b' and whose height is 'h' is A = (a + b) h. If one of the bases (say 'a'), height, and area are given, then we will just substitute these values in the above formula and solve it for the missing base (a) as follows: If the area and the bases of a trapezoid is known, then we can calculate its height using the formula, Area of trapezoid = (a + b) h; where 'a' and 'b' are the bases and 'h' is the height. entire area right over here, should really just :), Posted 5 years ago.
