A trapezoid has bases of 8 meters and 12 meters, and a height of 6 meters. What is its area? A. 60 square meters B. 72 square meters C. 48 square meters D. 36 square meters 相关知识点: 试题来源: 解析 A。梯形面积 = (上底 + 下底)×高÷2,即(8 + 12)×6÷2 = 60 平方米...
The volume of a trapezoidal prism is computed by multiplying the surface area of one of the trapezoid faces by the distance between the two trapezoids. This method, multiplying the surface area of a base by the height, is the same for computing the volume of any prism. The surface area o...
The quickest way to solve this problem is to note that, if you draw a line from C perpendicular to AD, you create a rectangle whose area is 16×8, or 128 square units. Because the trapezoid is slightly larger than the rectangle, the area must be slightly greater than 128. Only answer...
Example 3: If the area of the trapezoid is 120 inches and the lengths of the bases are 12 inches and 20 inches, find the height of the trapezoid using the trapezoid formula?Solution: Let us assume that the bases are a and b, and the height of the trapezoid is h. Using the given ...
These properties can be used to find the formulas of the angles, area, and perimeter of an isosceles trapezoid. Trapezoid Parallel Sides In quadrilaterals such as squares and rectangles, there are two sets of parallel sides. A trapezoid is different because only one set of sides (the bases)...
Now we are asked to find its area. Unfortunately, we are not given any formula for calculating the area of this kind of quadrilateral. (You might remember that its technical name is a trapezoid, but in fact we don't need to know anythingspecial about trapezoids to solve this problem.)...
Learn what concave and convex quadrilaterals are. See the properties of convex and concave quadrilaterals and find examples of each, such as concave trapezoids. Related to this Question What is a quadrilateral with no parallel sides? How is a rectangle a convex quadrilateral?
Trapezoid What is the formula for the area of an equilateral triangle inscribed in a circle? What is the difference between an equilateral triangle and an isosceles triangle? What is a regular parallelogram? Given a triangle with sides of 25, 9, 25, what type of triangle is it Equilateral,...
A quadrilateral is a trapezoid or a trapezium if 2 of its sides are parallel to each other. A quadrilateral is a parallelogram if 2 pairs of sides parallel to each other. Squares and Rectangles are special types of parallelograms. Below are some special properties.–All internal angles are ...
In American English, a trapezoid has at least one pair of parallel sides; in British English, a trapezium has no parallel sides.
