A trapezoid has a base of length 4, another base of length s, and a height of length s. A square has sides of length s. What is the value of s such that the area of the trapezoid and the area of the square are equal?

The above figure shows Square . is the midpoint of ; is the midpoint of ; is the midpoint of . Construct .

If Square has area , what is the area of Quadrilateral ?

Find the area of a trapezoid given bases of length 1 and 2 and height of 2.
