Approved. and even if it were 9, ChatGPT only added the trapezoidal face once rather than twice ("A_total = A_base + A_lateral"), which is kind of obviously wrong. In this case, we first need to calculate the height of the trapezoid. I'll try to explain and hope this explanation isn't too confusing! The surface area of a trapezoidal prism can be given with this formula: (b1+b2)h + PH. of those two numbers. Area of a Trapezoid = A = 1 2 h (a + b) Where: Click on the Advanced mode button to get the value of the area by entering the angles and the slant side. Options. In the US a trapezoid is a 4 sided figure with at least one set of parallel sides by some definitions, or exactly one set of parallel sides by other definitions. The most general formula for the surface area of any prism is: Total area = Lateral area + 2 Base area It depends on the data you're given as to how to proceed to determine both the lateral area and the base area. Direct link to KC's post By using the area of trap, Posted 7 years ago. area of the trapezoid should be in between Finally, apply the formula for the area of a trapezoid: A = (a + b) h / 2 = (4 + 1.675) 6 / 2 = 17.026 cm. When all the sides of the trapezoid are known, and we do not know the height we can find the area of the trapezoid. Then, if the trapezoid's height was 10 inches, you'd add that to 20 and get 30. Let us understand this with the help of an example. a rhombus as an area of 72 ft and the product of the diagonals is. Don't use ChatGPT to learn mathematics, and use it at your own peril if you try to cheat at homework with it. The surface area of a trapezoidal prism is calculated by multiplying the surface area of one of the prisms by two then adding the sum of the perimeter into the height of the trapezoidal prism. To find the area of a right trapezoid, use the formula: A = ( a + b ) x h/2. Therefore, the lateral surface area is: A_lateral = height perimeter A_lateral = 10 cm 130 cm A_lateral = 1300 cm, The total area of the prism is the sum of the area of the trapezoid base and the lateral surface area: A_total = A_base + A_lateral A_total = 540 cm + 1300 cm A_total = 1840 cm. like this that is exactly halfway in between As a trapezoidal prism has a curved surface as well, thus we can express its curved surface area as well as total surface area. This is when some good old trigonometry comes to the rescue! You can prove this by integrating $\int_0^h y(b + (a-b)\frac yh) dy$ and dividing by the area of the trapezoid.
