What is the area of the trapezoid below? 30 !

180 units²

Step-by-step explanation:

Let's find the length of the dashed line (which is the length of the trapezoid).  Use the Pythagorean Theorem:

7² + h² = 25², or h² = 625 - 49 = 576.  Thus, h = √576 = 24.

The average width of the trapezoid is:

         (7+4) + 4

w = = 15/2

               2

The area of a trapezoid is (average width of trapezoid)(length of trapezoid), and here that comes to:

        15

A = * 24 = 180 units²

          2

Hope this help!!!
