Answer 1

$\textbf {Hey there, here is the solution.}$

.............................................................................................

Area of the flower pots:

Area of the flower pot base = x² + 6x + 9 (Given)

Factorise:

Area of the flower pot base = (x + 3)²

.............................................................................................

Area of the rectangular area:

Area of the rectangular area = (x + 3) (7x + 21)

Factorise:

Area of the rectangular area = 7(x + 3) (x + 3)

Area of the rectangular area = 7(x + 3) ²

.............................................................................................

Number of flower pots:

Number of flower pots = 7(x + 3) ² ÷  (x + 3) ² = $\dfrac{7(x +3)^2}{(x+3)^2}$ = 7

.............................................................................................

Answer: 7 flower pots can be placed there.
