The altitude of the trapezoid is 5 m. Find the area. We find the total area by adding up the area of each of the three trapezoids: \text {Total area} = T_1 + T_2 + T_3 Total area = T 1 + T 2 + T 3. The area occupied by the surface of a trapezoidal prism is known as the surface area of a trapezoidal prism. where two of the sides are parallel to each other. This article was co-authored by wikiHow staff writer. Approved. It did get the lateral faces part right, which is pretty cool, I guess. The lateral surface area of the trapezoidal prism (LSA) = the sum of the areas of each rectangular surface around the base = (6+12+5+5)10 = 280 square cms. Hunter Rising is a wikiHow Staff Writer based in Los Angeles. The minimum amount of right angles a trapezoid can have is two. Learning this great, "I'm a grade 5 kid who doesn't know how to get the area of a trapezoid. As a trapezoidal prism has a curved surface as well, thus we can express its curved surface area as well as total surface area. The median's length is the average of the two base lengths: You can calculate the area when you know the median, it is just the median times the height: A trapezium (UK: trapezoid) is a quadrilateral with NO parallel sides. Area of a trapezoid is found with the formula, A= (a+b)/2 x h. Learn how to use the formula to find area of trapezoids.
