Answer:
C=14pi cm
A=49pi cm^2
Step-by-step explanation:
1) Circumference of a circle is 2piR and R=7cm
C=2pi(7)
C=14pi cm
2) Area of a circle is piR^2 and R=7cm
A=pi (7)^2
A=49pi cm^2
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
