Answer:
42 feet
Step-by-step explanation:
1) remeber how 1 foot=12 inches
we need to find "x" feet for 144 inches
so
[tex]\frac{1}{12}=\frac{x}{144}[/tex]
2) cross multiply
144=12x
divide both sides by 12
12=x
so 144 inches is 12 feet, we need to do the exact same thing for the width
[tex]\frac{1}{12} =\frac{x}{108}[/tex]
108=12x
9=x
the length is 12 feet and width is 9 feet
to find perimeter:
2(l)+2(w)
2*12+2*9
24+18=42
Hope this helps!
Here is what the answer is: 42 feet!!
How did I get it?; So, first we have to add the 108 + 108 (because there is 2 sides) and then add the 144 + 144 (because there is 2 sides).
Then, you get: 108 + 108 = 216 and 144 + 144 = 288. OK, add the 216 + 288. Afterwards, you will get 504. Then divide 504 / 12 because in 1 foot, is 12 inches.
50 / 12 = 42 feet. (When we go from small to big, we divided and when we go from big to small, we multiply)
I hope this helped :)
