Solution:
Given that,
The amount of paint needed to cover the walls of a room varies jointly as the perimeter of the room and the height of the wall
The formula for joint variation is:
Where,
z is the amount of paint needed
x is the perimter of room
y is the height of room
Room with a perimeter of 35 feet and 10 foot high walls requires 3.5 quarts of paint
Therefore,
find the amount of paint needed to cover the walls of a room with a perimeter of 55 feet and 8-foot walls
Substitute k = 0.01, x = 55 and y = 8 in joint variation formula
Thus, 4.4 quarts of paint needed to cover the walls of a room with a perimeter of 55 feet and 8-foot walls
