Step-by-step explanation:
Given parameters:
Length = 120yards
Width = 85yards
Unknown:
Length and width of another rectangular field with the same perimeter but a larger area = ?
Solution:
The key to solving this problem is to known that for any given length and width, the area of square is the greatest.
Length = 120yards New length = 100yards
Width = 85yards New width = 105yards
Now,
Area of the new dimension = 105 x 100 = 10500yd²
