An isosceles trapezoid has base angles of 45° and bases of lengths 9 and 15. the area of the trapezoid is 36 sq. units 67.5 sq. units 72 sq. units

36 sq. units

Step-by-step explanation:

Area of any Trapezoid can be found by the formula Area=

The base angles are given as 45 degrees so we have a 45 45 90 triangle .In 45 45 90 triangle legs are same so height = 3.

Area of trapezoid =

                            =
