Answer:
Step-by-step explanation:
Remark
Later on, in a not so distant future, you will learn that the maximum area of a rectangle can be obtained when you are dealing with a square.
So to get the maximum area, change the rectangle into a square. Leave the perimeter the same.
Formulas
Perimeter = 2L + 2W
Perimeter = 4*s for a square
Area = s^2
Givens
L = 115
P = 75
Solution
P = 2 * 115 + 2 * 75
P = 230 + 150
P = 380
Perimeter of a square
P = 4*s Substitute
4s = 380 Divide by 4
s = 95
Check
Area of original Rectangle = 115 * 75 = 8625
Area of the derived square = 95^2 = 9025
