Answer:
a=br/s
b=as/r
s= br/a
Step-by-step explanation:
Let's solve for a.
r=a/b s
Step 1: Multiply both sides by b.
br=as
Step 2: Flip the equation.
as=br
Step 3: Divide both sides by s.
as/s=br/s
a=br/s
and do the same for b and s

We know that
the screen aspect ratio=width/height-------> height=width/screen aspect ratio<span>
in this problem
</span>the screen aspect ratio=16/9
height=?
width=50 in
height=width/screen aspect ratio-----> 50/(16/9)---> 50*(9/16)---> 28.125 in
the answer is
28.1 in
