area of the kitchen = 81
are of the pantry = 1/9 of the kitchen (given)
= 81/9 = 9
width of the pantry = 3 so length of the pantry = 9/3 = 3
so, pantry is 3 feet long.

Answer:
Step-by-step explanation:
A2 = L × 3 square feet----(2)
But given condition in the problem is
9 times of area of the pantry = Area of the kitchen
9× A2 = A1
From (1) and (2)
9 × L × 3 = 81
L= 81/(9 × 3)
After cancellation we get
L = 3 feet
Therefore, length of the Brinn's pantry = L = 3 feet
