1 2 A = h(b1 + b2) Area of a trapezoid 1 2 A = (18)(20 + 36) Substitute 18 for h, 20 for b1, and 36 for b2. 10-2Īreas of Trapezoids, Rhombuses, and Kites Lesson 10-2 Notes 10-2Ī car window is shaped like the trapezoid shown. Areas of Parallelograms and Triangles Lesson 10-1 Lesson Quiz 150 ft2 15 m2 24 square units 187 in.2 6 cm 10-2Īreas of Trapezoids, Rhombuses, and Kites Lesson 10-2 Notes The height of a trapezoid is the perpendicular distance hbetween the bases. Find the total area of the shaded regions. A rectangular flag is divided into four regions by its diagonals. Find the height corresponding to the 6-cm base. The height corresponding to the 8-cm base is 4.5 cm. So, add the three areas: 3 + 4.5 + 6 = 13.5 units2. By Theorem 1–10, the area of a region is the sum of the area of the nonoverlapping parts. The area A of the rectangle is bh = (2)(3) = 6. The area A of the triangle on the right is bh = (3)(3) = 4.5. The area A of the triangle on the left is bh = (2)(3) = 3. This forms two triangles and a rectangle between them. Draw two segments, one from A perpendicular to CD and the other from B perpendicular to CD. So, add the three areas: 1 + 2 + 4 = 7 units2. The area A of the rectangle is bh = (2)(2) = 4. The area A of the triangle on the right is bh = (2)(2) = 2. The area A of the triangle on the left is bh = (1)(2) = 1. Draw two segments, one from M perpendicular to CB and the other from K perpendicular to CB.

I usually print the PDF for students to use before or while they complete the form. I use these assignments as class work or homework. You will also receive a PDF document that includes the exact same questions as the Google Form. TpT will automatically add this form & file to your drive. Questions are scaffolded, such that all information is given in the first few problems and then pre-requisite knowledge may be used in more challenging problems, such as: the Pythagorean Theorem, side length relationships within 45-45-90 and 30-60-90 triangles.
There are 5 problems for each type of parallelogram. This self-grading, digital assignment provides students with practice calculating the area of trapezoids, rhombuses, and kites.
