Answer:

7

Step-by-step explanation:

Using the definition

nP_{r} = \frac{n!}{(n-r)!}

where n! = n(n - 1)(n - 2)..... 3 × 2 × 1

Then

7P_{1} = \frac{7!}{(7-1)!} = \frac{7!}{6!} ← cancel out the multiples 6 ×5 × 4 × 3 × 2 × 1 , then

7P_{1} = 7

The area of the David's pantry = 10 square feet.

The length of the pantry = 5 feet.

<h3>Define the term area of the rectangle?</h3>
  • The territory inhabited by a rectangle inside its 4 sides or limits is known as its area.
  • The area of such a rectangle is determined by its sides. Essentially, the formula calculating area is equivalent to the product of the rectangle's length and breadth.

For the given question.

  • David's kitchen is 60 square feet in size.
  • The kitchen is six times the size of the living room.

Thus,

Area of kitchen  = 6 x area of the pantry

60 = 6 x area of the pantry

area of the pantry = 60 / 6 = 10 square feet.

Area of the pantry = length x breadth

10 = length x 2

length = 10/2 = 5 feet.

Thus, the length of the pantry is found as the 5 feet.
