#Trapezoid perimeter and area worksheets how to

You now know how to calculate the perimeter of a trapezoid - add all the sides and bases of the trapezoid.Īnd, you know how to calculate the area of a trapezoid using the trapezoid area formula and the lengths for the base and the height.įor extra credit, it should now be clear why the formula for the area works the way it does. Putting it all together gives us the area of the trapezoid to be:Ĭalculating the Area and Perimeter of a Trapezoid The a and b in the formula stand for the base and the height of the trapezoid, which we know to be DC = 4.5 and AB = 2. ABCD is known as a right trapezoid because it contains a right angle. Use it easy as the dimensions in triangle area. Use this worksheet to help students describe and create trapezoid patterns. parallelograms but the diameter, determining the angle, perimeter and the pieces and trapezoids worksheet. Geometry 8 2 Worksheet Find Area Trapezoid Rhombus. Each exercise provides a drawing of the trapezoid as well as the height and the width of its bases.

It is the same as the right hand side of the trapezoid because the side connecting vertices B and C is at a right angle, or perpendicular, to both the bases. Classify trapezoids and calculate the perimeter and area of trapezoids with this set of printable worksheets. In this diagram, we see that the height of the trapezoid is BC, or 2. Let’s practice using the formula for the area of a trapezoid. The height of the base of the parallelogram is the sum of the top base and the bottom base of the trapezoid, which in this case is 2 + 4.5 = 6.5. As shown in this diagram, the height of the parallelogram is the same as the height of the trapezoid (both are equal to 2). To find the area of a parallelogram, we also need the height. See the diagram here how the orange trapezoid is just the blue trapezoid flipped on itself: The formula multiples the height of a trapezoid h with the sum of the two bases a and b, then divides by 2 because the area of the trapezoid is always one half of the parallelogram formed by flipping the trapezoid on itself. To find the area of a trapezoid, we’ll use this formula: The perimeter of this trapezoid above is 2 + 2 + 4.5 + 3 = 11.5.

The length of the right side length, BC, is 2.

The length of the left side length, AD, is 3.

The length of the bottom base, DC, is 4.5. Perimeter and Area of Polygons Worksheets Find the Perimeter of a Triangle, Perimeter of a Rectangle, Area of a Triangle, Area of a Trapezoid and more.

In this trapezoid ABCD, we see that the perimeter of the trapezoid is the sum of AB, BC, DC, and AD: To find the perimeter, or the total length of all the sides of the trapezoid, we simply add the lengths of each side. We know that polygon ABCD is trapezoidal because the top and bottom base of the trapezoid are parallel.

How do we go about finding the perimeter and area of a trapezoid? Read through for examples. Outside of North America, trapezoids may be referred to as trapeziums. A trapezoid is a quadrilateral, or a polygon with four sides, with one pair of parallel sides and one pair of non-parallel sides.
