Step-by-step explanation:
Answer:
42
Step-by-step explanation:
The permutation formula is P(n, r) = n! / (n - r)!. We know that n = 7 and r = 2 so we can write:
7! / (7 - 2)!
= 7! / 5!
= 7 * 6 * 5 * 4 * 3 * 2 * 1 / 5 * 4 * 3 * 2 * 1
= 7 * 6 (5 * 4 * 3 * 2 * 1 cancels out)
= 42
Answer:
Area of table cloth = 49/9 m² or 5.44 m²
Step-by-step explanation:
Given:
Side of table cloth =
= 7/3 m
Shape of cloth is square
Find:
Area of table cloth
Computation:
Area of square = side²
So,
Area of table cloth = side²
Area of table cloth = (7/3)²
Area of table cloth = 49/9 m² or 5.44 m²
