Donner les valeurs exactes de AH puis de AC. Donner ensuite les valeurs approchées au millième. A 11,5 cm C 6,9 cm H 15 cm Merci!​

what i would say the best answer is a. 40.5

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.
