We can find the height of the trapezoid (h) using the Pythagorean theorem: h + ((b-a+h')/2) = h' h = sqrt(h'^2 - ((b-a+h')/2)) h = sqrt(37^2 - ((20-60+37)/2)^2) cm h = sqrt(37^2 - 343) cm h = sqrt(1296) - sqrt(343) cm h = 28 - 19 cm h = 9 cm, Now we can plug in the values and calculate the area of the trapezoid: A = (60 cm + 20 cm) 9 cm / 2 A = 540 cm.

As a small thank you, wed like to offer you a $30 gift card (valid at GoNift.com). Direct link to Midnight the wolf's post how do you discover the a, Posted 3 years ago. like this that is exactly halfway in between . The bases are given as, a = 32 cm; b = 12 cm; the height is h = 5 cm. Visual in the figure below: To get the result, we use the area of a trapezoid formula: A = (a + b) h / 2 and place a = 8 m, b = 1 m, and h = 5 m inside it. L = al +cl + bl + dl Substitute each piece into the equation: In this formula, "b1" and "b2" stand for the length of the bases of the trapezoid. Step 3: Add the respective values in the formula, (a+b+c+d) H or PH, and you will get the lateral surface area of the hexagonal prism. area difference between the two rectangles-- and let Step 5: Put the values in the formula, (b1+b2)h + Lateral Surface Area(PH), to obtain the final value of the total surface area of the hexagonal prism. two lengths, 6 plus 2 over 2 is 4. ", calculation, explained so well, made it much easier to do the job! It is used while evaluating the area under the curve, under that trapezoidal rule. Kristina Frischholz 4 years ago What is the formula for a trapezoid? Find the lateral surface area of the prism: The lateral surface area of a prism is the sum of the areas of all its lateral faces. The area occupied by the surface of a trapezoidal prism is known as the surface area of a trapezoidal prism. a rhombus as an area of 72 ft and the product of the diagonals is. The Perimeter is the sum of all side lengths: Perimeter = 5 cm + 12 cm + 4 cm + 15 cm = 36 cm. #S = h(a + b) + al + cl + bl + dl#, Distribute and Rearrange: The US and UK have their definitions swapped over, like this: 9131, 9132, 9133, 9134, 9135, 9136, 9137, 9138, 9139, 9140.
