Find the smallest perimeter and the dimensions for a rectangle with an area of 225 in^2

To solve this, let the dimensions be x and y. We know that the area is 225. So, x * y = 225 

Let the perimeter be denoted as P.

P = 2x + 2y 

sine y = 225/x 

P = 2x + 450/x 

P' = 2 - 450/x^2 

P'' = + 900/x^3 

Put P' = 0 

then x = 15 

at x =15 P'' is positive 

So the minimum perimeter, will be:
P = 2 (15 + 15) = 60 cm

i believe it is b and c. (side note, i got the same computer from k-12 lol i’m in 8th grade and this is my first year, will it get

step-by-step explanation:

chemists are often responsible for designing a chemical reaction and analyzing the products obtained from it. one significant part of designing a chemical reaction is determining the amount of each reactant that is needed and the amount of each product that will be produced. in order to do so, chemists use stoichiometry, the quantitative relationships between reactants and products.
