Answer:
The answer is 40.8 m.
Step-by-step explanation:
To find the perimeter of the rectangle, use the formula P= 2(
)+ 2(
). Plug in the information given in the question, and the equation will look like
P= 2(12m) + 2(8.4m)
Solve the equation, and the final answer will be 40.8 m.
The coordinates are (-3/4, 1/2)
this is also equivalent to (-0.75, 0.5) if that helps understand if further!
Since the total of exterior angles of a plane figure is always 360, you would divide 360 by 20 which gives you 18
