Answer:2.3

Step-by-step explanation:

Cut the the shape into a right triangle and a rectangle

Tri: find measure of the base

sin(45)= opp/hyp

          = x/1.8

        1.8 *sin (45)  = x

x = 1.3

base of tri = 1.3

Area of tri = 1/2bh

                     1/2(1.3)(1.3)

                    =0.845

Area of rectangle: 1.1*1.3=1.43

Total area = 1.43+0.845

                  =2.245

                  =2.3m^2
