Brainlet here

Can you solve this problem Veeky Forums. I wasted hours in this shit I couldn't solve it. Am I a brainlet?
Pic related it's exercise 52

What class is this for?

Determine whether a square or a triangle gives more surface area for every foot of fence

Make the less efficient shape tiny and the more efficient shape huge.

Calculus I

I need to have both. The problem states you need 2 pens

Oh I got what you mean but still doesn't work

It's an optimization problem. Try some stuff in that area and if you still can't get it I'll help you, but you need to show some work first.

Start by making a square and a triangle with sides of 14.2857ft in length and go from there

Aka what in saying is find the formula for the areas of a triangle and square, then find their max (where is the graph increasing then decreasing) and you should be able to go from there.

if i can figure out what you're saying without taking calculus, does that mean i'm a genius?
