arachidonic acid is made in the body by the enzymes d5d,d6d and elongase from Linolic acid (LA). AA is not essential, LA is essential. Dietary arachidonic acid is present in red meat and poses a risk by promoting inflammatory reactions.

The perimeter would be 28 centimeters. This can be seen because all 4 sides are equal in a square, and the area is equal to two adjacent sides multiplied, so all you have to do is find the square root of 49 which is 7, so this is the length of each side, and the total preimeter is 4 times this which is 28.
