Exercise 1
Find the area of the following trapezoid:
Exercise 2
A wooded area is in the shape of a trapezoid whose bases measure 
and 
and its height is 
. A 4 m wide walkway is constructed which runs perpendicular from the two bases. Calculate the area of the wooded area after the addition of the walkway.
Exercise 3
A line connects the midpoint of BC (Point E), with Point D in the square ABCD. Calculate the area of the acquired trapezoid shape if the square has a side of 
.
Exercise 4
The perimeter of an isosceles trapezoid is 
and the bases are 
and 
in length. Calculate the length of the non-parallel sides of the trapezoid and its area.
Exercise 5
If non-parallel sides of an isosceles trapezoid are prolonged, an equilateral triangle with sides of 
would be formed. Knowing that the trapezoid is half the height of the triangle, calculate the area of the trapezoid.
Exercise 6
Find the height of the following isosceles trapezoid:
Exercise 7
Calculate the oblique side of the right trapezoid:
