The answer is 50 ft. In order to find the perimeter, you must find the length of the left side. After some deduction 
, you can find that the base of the triangle is 6 ft. Then using the Pythagorean Theorem, or 3-4-5 right triangles, you can find that the height of the triangle and rectangle is 8 ft. 
Once you find that the last side is 8 ft, you can add
to get an answer of 50 ft. for the perimeter.

We can then use the Pythagorean Theorem to find the right portion of the bottom base. We can then use this value to determine the left portion.
Using Pythagorean Theorem again, we can calculate the left leg to be 20. That means we now know all four sides. The perimeter is simply the sum.

An isosceles trapezoid has two bases that are parallel to each other. The larger base is 
times greater than the smaller base. The smaller base has a length of 
inches and the length of non-parallel sides of the trapezoid have a length of 
inches.

To find the perimeter of this trapezoid, first find the length of the larger base. Then, find the sum of all of the sides. It's important to note that since this is an isosceles trapezoid, both of the non-parallel sides will have the same length.
The solution is:
The smaller base is equal to 
inches. Thus, the larger base is equal to:
, where

A quadrilateral has four sides and four angles, but no restrictions on how the lengths or measures are related. Thus, quadrilateral is the right answer.
In squares and rectangles, all four angles measure 90 degrees; thus the angles are all of equal measurements, making square and rectangle incorrect answer choices. A rhombus has two sets of angles of equal measurements, and would also be incorrect.
