Answer: 
Step-by-step explanation:
Given : Two opposite sides of a rectangle are each of length x.
Let the other adjacent side be y.
The perimeter of the rectangle is 12 units.
Perimeter of rectangle is given by :-

The area of rectangle is given by :-

Hence, the area as a function x = 
Answer:
square feet
Step-by-step explanation:
Circumference = 2πr
13π = 2πr
=r
Area = πr²
π ×
² =
π square feet
Answer:
272.3 or just 272
Step-by-step explanation:
To find answer first find the area of the circle, then add the 18.
A=r*r*3.14 (pi) = 9*9*3.14=254.34
254.34+18=272.34
Hope this helps!!! :)
The rectangle has an area of 18x8 = 144 sq in. The circle has an area of (pi)r^2 or (pi)3^2 =28.27sq in. Subtract 144 - 28.27 = 115.73
Answer:
8000/100+80/100=80+0.8=80.8
