Hi, you haven't provided the programing language in which you need the code, I'll explain how to do it using Python, and you can follow the same logic to make a program in the programing language that you need.
Answer:
import math
def rectangle(perimeter, area):
l1_1 = (perimeter+math.sqrt((perimeter**2)-(16*area)))/4
l1_2 = (perimeter-math.sqrt((perimeter**2)-(16*area)))/4
l2_1 = area/l1_1
l2_2 = area/l1_2
print(l1_1,l2_1)
print(l1_2,l2_2)
if l1_1.is_integer() and l2_1.is_integer() and l1_1>0 and l2_1>0:
return(int(max(l1_1,l2_1)))
elif l1_2.is_integer() and l2_2.is_integer() and l1_2>0 and l2_2>0:
return(int(max(l1_2,l2_2)))
else:
return(None)
Explanation:
- We import math to make basic operations
- We define the rectangle function that receives perimeter and area
- We calculate one of the sides (l1_1) of the rectangle using the quadratic equation to solve 2h^2 - ph + 2a = 0
- We calculate the second root of the quadratic equation for the same side (l1_2)
- We calculate the second side of the rectangle using the first root on w = a/h
- We calculate the second side of the rectangle using the second root on w= a/h
- We verify that each component of the first result (l1_1, l2_1) is an integer (using the build-in method .is_integer) and greater than 0, if True we return the maximum value between them (using the max function) as w
- If the first pair of sides evaluate to False we check the second root of the equation and if they meet the specification we return the max value
- if all the if statements evaluate to false we return None to indicate that not positive or integer sides were found
Answer:
name = re.search(r"^([\w \.-]), ([\w \.-])$", list_name)
Explanation:
Regular expression is used to simplify the mode in which items in a data structure are for. It uses wildcards as shortcuts.
The python module for regular expression is 're'. The import statement is used to get the module and the search() method of the module is used to get the one matching item while the findall() method is used to get a list of all the matching items in a data structure.

Explanation:
A webpage gets a new modification date whenever any change is made. This is irrespective of whether the change is large or small, significant or insignificant. Any update to the webpage will change its modification date. But this change will not be carried out automatically everyday unless an actual modification is carried out on that day.Otherwise it will continue to carry the modification date corresponding to the day of last update.
