Answer:
Answer is 25ft.
Step-by-step explanation:
l=20ft.
h=16ft.
let 'w' be x.
then
l=√w2+h2
or l=√x2+(16)2
squareing on both side.
or (20)2=√(x+16)2
or 400=x+16
or x=400/16
or x=25.
so that the value of W is 25ft.
I think you mean mixed number fractions. So what you do is just subtract, both the fraction and also the number. So for example 1 2/3 - 1 1/3 is just 1/3 because you subtracted both of them
