Let c ∈ (a, b) and let d ∈ r. define f : [a, b] → r as ( d if x = c, f (x) : = 0 if x = c. prove that f ∈ r[a, b] and compute r b a f using the definition of the integral (but feel free to use the propositions of this section).

step-by-step explanation:

the given 6 = w/p is equivalent to 6p = w, where w is the total area of the walls and p is the area covered by a single can of paint.

knowing that 6 cans of paint will be needed, 6p = w becomes 6(6) = w = 36.   this tells us that the total area to be painted is 36 square units.
