The trapezoid's altitude is 12 per https://en.wikipedia.org/wiki/Trapezoid#Midsegment_and_height. Indulging in rote learning, you are likely to forget concepts. In this case, we first need to calculate the height of the trapezoid. The unit of the surface area of a trapezoidal prism is given in cm2, m2, ft, or cubits2. Bogna Szyk Angles Check out 23 similar 2d So you could imagine that being If you have asked it a math question that cannot be immediately easily googled then it is incredibly unlikely to have answered it correctly. As illustrated above, the area of a right trapezoid is A = ah_2-1/2(h_2-h_1)a (1) = 1/2a(h_1+h_2). According to the trapezoid area formula, the area of a trapezoid is equal to half the product of the height and the sum . By using the area of trapizoid equation, A=1/2*h*(b1+b2), is this a second correct way to solve it 2*3+6*3*1/2. To find the area of a right trapezoid, use the formula: A = ( a + b ) x h/2. Therefore, the total area of the prism is 1840 cm. wikiHow, Inc. is the copyright holder of this image under U.S. and international copyright laws. is, given the dimensions that they've given us, what The surface area of any three-dimensional geometrical shape is the sum of the surfaces of that enclosed solid which equals the areas of all of the faces. When all the sides of the trapezoid are known, and we do not know the height we can find the area of the trapezoid. Post all of your math-learning resources here. Area of trapezoid = 1/2 (sum of the parallel sides) (Distance between the parallel sides) 440 = 1/2 (30 + 14) h. h = (440 2)/44 cm.
