<h2>correct Question :</h2>- A rectangle has a side length and wide of 9 centimeters and 6 centimeters. What is the area of the rectangle
- A rectangle has a side length and wide of 9
- centimeters and 6 centimeters.
- area of rectangle.
- A = l × w
where,
- A = area of rectangle
- l = lenth of rectangle
- W = wide of rectangle
⟼ l = 9 cm
⟼ W = 6 cm
⟼ Area = l × b
⟼ Area = 9 × 6 cm
⟼ Area = 54 cm².
∴ the area of rectangle is 54 cm².

Step-by-step explanation:
The nth term of an AP is
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Given a₅ is double a₇ , then
a₁ + 4d = 2(a₁ + 6d) , that is
a₁ + 4d = 2a₁ + 12d ( subtract a₁ from both sides )
4d = a₁ + 12d ( subtract 12d from both sides )
- 8d = a₁
The sum of n terms of an AP is
=
[ 2a₁ + (n - 1)d ] , substitute values
=
( 2(- 8d) + 16d)
= 8.5(- 16d + 16d)
= 8.5 × 0
= 0
