Answer:

Width = 4.5

Length = 7.5

Step-by-step explanation:

The perimeter is two times the length plus two times the width.

So 2(x+3) + 2x = 24 is the equation to solve.

2x+6+2x = 24

4x = 24-6

4x = 18

x = 9/2= 4.5

So the width = 4.5

Length = 4.5+3 = 7.5

Answer:

Length = 7.5 and width =- 4.5.

Step-by-step explanation:

We have the equation:

P = 2L  + 2W   where P = perimeter, L = length and W = width.

Here P = 24, L = x + 3 and W = x

So plugging in the given values:

24 = 2(x + 3) + 2x

4x + 6 = 24

4x = 24 - 6 = 18

x = 4.5.

So  the dimension ar length = x + 3 = 7.5 and width = 4.5.
