NEED HELP ASAP GIVING 33 POINTS AND PLZ SHOW WORK DONT DO 7-8

1) 1924m²

2) a = (b x h) / 2

(5 x 12) = 60

60 / 2 = 30in²

30in² x 2 = 60in²

area of upper rectangle =

a = l x w

13 x 8 = 104in

area of backer rectangle =

a = l x w

12 x 8 = 96in

60in² + 104 + 96 = 260in²

(thats all i know sorry :/)

δabc ≅ δdcb by sas because

db ≅ ac . . given (side)

bc ≅ bc . . reflexive property (side)

∠dbc ≅ ∠ acb . . alternate interior angles where transversal bc crosses parallel lines bd and ac (included angle)
