Rectangle area = (rectangle width) x (rectangle height)
A = lw Area of a rectangle = length times width
The area of rectangle is : 35.0
effectiveness of a fin is the rate of heat transfered by the fin to the rate of heat transfered without the fin.By knowing the effectiveness we can determine how a fin increases the heat transfer rate when compared to the normal surface without a fin.Whereas by determining the efficiency of a fin we can know the heat transfering capacity of the fin material. both are ratio to heat transfer by fin but, in effectiveness we take base area of fin, other hand in fin efficiency we choose fin area except base area or area which contact with surrounding.
To fin the area of a square or rectangle you use the equation LxW=A. 30x30=900 5x200=1000 Since 1000 is more than 900, a rectangle with the length of 5 feet and the width of 200 feet is bigger.
It's half the area of a rectangle
The area of rectangle is : 168.0
The area of rectangle is : 30.0
The area of rectangle is : 48.0
The area of rectangle is : 45.0
Area of rectangle with part of the shape missing = area of rectangle (lengthxwidth)-area of missing part.
The area of rectangle is : 72.0
