The perimeter of a rectangle is 2l+2w. So here we have:
2(11)+2(3x)=34

Next, we distribute:
22+6x=34

Get the x alone. Start by subtracting 22 from both sides.
22-22+6x=34-22
6x=12

Divide both sides by 6 to solve for x:
6x/6=12/6
x=2

Hope this helps.

The value of x is 2.

What is perimeter of rectangle?

Perimeter of rectangle = 2* ( length + breadth)

Given:

l= 11 cm ,  b= 3x, Perimeter= 34 cm

Now,

Perimeter of rectangle

34= 2(l + b)

34= 2* ( 11+ 3x)

17= 11 + 3x

6 = 3x

x=2
