## Exercise 1

Find the area of the following trapezoid:

## Exercise 2

A wooded area is in the shape of a a trapezoid whose bases measure 128 m and 92 m and its height is 40 m. 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 4 m.

## Exercise 4

The perimeter of an isosceles trapezoid is 110 m and the bases are 40 and 30 m 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 6 cm 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:

## Solution of exercise 1

Find the area of the following trapezoid:

## Solution of exercise 2

A wooded area is in the shape of a a trapezoid whose bases measure 128 m and 92 m and its height is 40 m. 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.

A_{Z} = A_{Trapezoid} − A_{Walk}
