What is the area of the figure below?

The horizontal legs of the upper triangles are equal in length to the vertical leg (2.5 m) since those triangles are isosceles right triangles.

The overall area is half the product of the lengths of the diagonals, so is
.. A = (1/2)(2*2.5 m)(2.5 m +6 m)
.. = (2.5 m)*(8.5 m)
.. = 21.25 m^2

The 3rd selection is appropriate.

This polygon has 4 sides
180(4-2) = 180(2) = 360 degree
80+90+2x + 3x = 360
170+5x = 360
5x = 190
x= 38
measure of angle t is 2(38)= 76
the answer is c. trust me
hope this !
