Answer 1

Answer:

20. J, 21. B

Step-by-step explanation:

20. P = 15 (2) + 8 (2)

      P = 36 ft.

21. 15 - 6 = 9 ft.

Answer 2

Answer:

$\Large \boxed{\mathrm{20. \ 46 \ feet}} \\ \\ \\ \Large \boxed{\mathrm{21. \ 9 \ feet}}$

Step-by-step explanation:

The perimeter of a rectangle is the sum of all its sides.

$\Rightarrow 15+8+15+8$

$\Rightarrow 46$

The distance between the window and the foot of the bed is:

length of the room - length of the bed

$\Rightarrow 15 - 6$

$\Rightarrow 9$
