Answer:

8.64

Step-by-step explanation:

tge blackboard is 2 [tex]1\\-\\2[/tex]m long and 1 [tex]1\\-\\2[/tex]m wide

and the wooden frame around it is 8cm

8cm = 0.08m

the length of the frame is

1 [tex]1\\-\\2[/tex] +0.08 x 2 = 2.66m (plus)

the width of frame is

1 [tex]1\\-\\2[/tex] + 0.08 x 2 = 1.66m

tge perimeter is

(2.66 + 1.66) 2 = 8.64
