Answer:
Width is 14 ft, length is 28 ft
Step-by-step explanation:
We know that the length is twice as long as the width. This can be represented by L=2W.
The equation to solve this is 84=W+W+L+L. We can replace both the L variables with 2W, since that is what L equals.
84=W+W+2W+2W. We simplifiy to get 84=6W. We divide 84 by 6 and get W=14.
Now that we know the width, finding the length is easier. L=2(14). L=28 ft.
To check our math we can do 28+28+14+14. 56+28=84 ft.
Therefore, the width is 14 ft and the length is 28 ft.

Answer:
a.
Step-by-step explanation:
answer ko dyan is letter a ehh
All the triangles are similar, so you have ...
(short side)/(long side) = 3/(CD) = (CD)/12
Multiplying by 12(CD) gives
(CD)² = 3*12 = 36
CD = √36 = 6
The appropriate choice is ...
A) 6
