We find the second side of the rectangle, if it is 3m more first.
a = 6 m + 3 m = 9 m.
To calculate the area of the rectangle, you need to multiply one side to the second.
S = 6 m * 9 m = 54 m².
The perimeter of the rectangle is equal to the sum of the lengths of both sides multiplied by 2.
P = (6 m + 9 m) * 2 = 30 m.
Answer: The area is 54 m², the perimeter is equal to 30 m.
