Let x = width
Then, x + 3 = length 
So, 2x + 2(x + 3) = 26   
   2x + 2x + 6 = 26 
   4x = 20     
x = 5width = x = 5m and length = x + 3 = 8m Area = (length)(width) = (5)(8) =
40 m2

East Campus West Campus Total

Passed (84*100)/22=42 (84*100)/200 =42 84

Failed (116*100)/200=58 (116*100)/22=58 116

Total 100 100 200

Passed = 84×100/200

= 42

One circular table has a diameter of 9 ft, and another circular table has a diameter of 20 ft. How much greater is the area of t
morpeh [17]
Smaller circle:
diameter = 9 ft
radius = diameter/2 = (9 ft)/2 = 4.5 ft
A = pi(r^2) = 3.14159 * (4.5 ft)^2 = 63.62 ft^2

Larger circle:
diameter = 20 ft
radius = diameter/2 = (20 ft)/2 = 10 ft
A = pi(r^2) = 3.14159 * (10 ft)^2 = 314.159 ft^2

Difference = larger are - smaller area

Difference = 314.16 ft^2 - 63.62 ft^2 = 250.54 ft^2

Answer: About 251 ft^2
