Answer:
The value of x is 3.
Length of the rectangle = 3×3 = 9 cm
Step-by-step explanation:
We are given the following information in the question:
Perimeter of rectangle = 24 cm
Length of the rectangle = 3x cm
Width of the rectangle = 3 cm
Formula:
Perimeter of rectangle = [tex]2\times (Length + Width)[/tex]
Putting all the values, we have:
[tex]24 = 2\times (3x+3)\\24 = 6x + 6\\18 = 6x\\x = 3[/tex]
Hence, Length of the rectangle = 3×3 = 9 cm
