- What is the perimeter of the trapezoid?
- What is the area of the trapezoid?
- Use the isosceles trapezoid to show that the area of this trapezoid can also be written as the sum of the area of
the two triangles and the rectangle in the middle. Write the formula and then reduce it to equal^12 h(b 1 +b 2 )or
h
2 (b^1 +b^2 ). - QuadrilateralABCDhas verticesA(− 2 , 0 ),B( 0 , 2 ),C( 4 , 2 ), andD( 0 ,− 2 ). Show thatABCDis a trapezoid and
find its area.Leave your answer in simplest radical form.
