Answer:
Minimum area is : 1 * 35 = 35
Maximum area is : 19 * 17 = 323
Step-by-step explanation:
The parameter (P) of rectangle is calculated using:
P = 2(a+b)
We are given that,
P = 72
=> 2(a+b) = 72
=> a+b = 36
In rectangle, the lengths of both sides are different and a whole number (as mentioned in question), Therefore, the length of smaller side a can be varied from 1 to 17. Similarly, the length of larger side varies from 19 to 35.
The area can be easily calculated using a*b.
Minimum area is : 1 * 35 = 35
Maximum area is : 19 * 17 = 323
