例子问题# 11 :Quadrilaterals
This figure is an isosceles trapezoid with bases of 6 in and 18 in and a side of 10 in.
What is the perimeter of the isoceles trapezoid (in.)?
The perimeter of the isoceles trapezoid is the sum of all the sides. You can assume the left side is also 10 in. because it is an isoceles trapezoid.

Example Question #3 :How To Find The Perimeter Of A Trapezoid
Find the perimeter of the following trapezoid:
Use the formula fortriangles in order to find the lengths of all the sides and bases.
The formula is:
Whereis the length of the side opposite the.
Beginning with theside, if we were to create atriangle, the length of the base is, and the height is.
Creating anothertriangle on the left, we find the height is, the length of the base is, and the side is.
