The measure of the width is 11ft
and the measure of the length is:
11+6=17ft
Answer:

Step-by-step explanation:
First, multiply the two denominators together to get the shared denominator, which will allow you to actually subtract the two numbers. 4 × 8 = 32, so the shared denominator will be 32.
Then, cross-multiply. 11 × 8 = 88, so
becomes
. 3 × 4 = 12, so
becomes
.
Now, you can subtract. 
Finally, simplify.
. The final difference is
.
-19.2
12/(-5/8) means 12*(-8/5)
12*8=96
96/5=19.2
don’t forget the negative sign
so
-19.2
