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.
