Web8 nov. 2015 · If we denote one side of the rectangle with a, and the other with b we can write, that: a ⋅ b = 16. so we can write, that b = 16 a. Now we can write perimeter P as a function of a. P = 2 ⋅ (a + 16 a) We are looking for the smallest perimeter, so we have to calculate derivative: P (a) = 2a + 32 a. P '(a) = 2 + ( −32 a2) Web2 feb. 2024 · The perimeter of a rectangle equation is P= (a+b+a+b), which is basically a measure of all sides. In a simplified form: P=2× (a+b).
