Answer:

Missing side = 3 m

Perimeter = 18 m

Explanation:

Formula for the area of a rectangle:

• The formula for the area of a rectangle is given by:

A = lw, where

• A is the area in units squared,

• l is the length

• And w is the width.

Finding w, the width of the rectangle:

  • Since a rectangle's area is simply the product of its sides, we can call the other side the rectangle's width.
  • Since we know that the area is 18 m^2, we can plug in 6 for l to find w, the width of the rectangle:

(18 = 6w) / 6

3 = w

Thus, the width is 3 m.

Finding the perimeter:

The formula for the perimeter is given by:

P = 2l + 2w, where

• P is the perimeter,

• l is the length,

• and w is the width.

Thus, we can find P, the rectangle’s perimeter by plugging in 6 for l and w for w in the rectangle perimeter formula:

P = 2(6) + 2(3)

P = 12 + 6

P = 18

Thus, the rectangle’s perimeter is 18 m.

Explanation:

Area = width X height

18 = width x six shows width = 3 m

Perimeter = 2 X ( six + three) = ........ meters
