Option A and Option F
The expressions that represent the perimeter of rectangle are 4s + 1 and 
<em><u>Solution:</u></em>
From figure,
Length = s
Width = 
<em><u>The perimeter of rectangle is given as:</u></em>
perimeter = 2(length + width)
Substituting the values we get,

Thus option F is correct
On further simplification,

Thus Option A is correct
No because 30 minutes past 4 is 4:30. If he was still watching at 5:00 it would be more than double
The area would be 324 yards square. Since the height is already found, you multiply 15 by 21 2/3 yards.
Hope this helped :)
Wears the picture i know how to solve it
