how do you find the least perimeter for this area
a=30cm2 using whole numbers
:
Max area for min perimeter occurs when it's a square
= 5.477, not an integer
therefore the closest we can get is:
6 by 5 would be min perimeter of 22 cm
:
the further we get away form a square, the greater the perimeter
:
The other factors of 30: 10 by 3; 26 cm
and
another pair of factors: 15 by 2; 34 cm
and
one more pair of factors: 30 by 1: 62 cm
