Answer 2

The value of x is 3.

Length of the rectangle = 3×3 = 9 cm

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 =
`2* (Length + Width)`

Putting all the values, we have:

`24 = 2* (3x+3)\\24 = 6x + 6\\18 = 6x\\x = 3`

Hence, Length of the rectangle = 3×3 = 9 cm
