Answer:

Step-by-step explanation:

By applying Pythagoras theorem in ΔEGD,

ED² = EG² + GD²

y² = 5² + 2²

y = √29

y = 5.39

By applying cosine rule in ΔBCD,

cos(28.3)° = [tex]\frac{x}{19}[/tex]

x = 19cos(28.3)

x = 16.73"

Area of ABCDE = Area of trapezoid ABDE + Area of triangle BCD

                          = [tex]\frac{1}{2}(15+19)5+\frac{1}{2}(16.73)(9)[/tex]

                          = 85 + 75.28

                          = 160.28 square inch

Perimeter of ABCDE = AB + BC + CD + DE + AE

                                  = 5.39 + 16.73 + 9 + 5.39 + 15

                                  = 51.51"
