The perimeter of the rectangle is 28 units. What is the value of w?

Solution:

We know that

Perimeter = 2 (L + W)

It is given that 

Perimeter of the rectangle = 28 units

Here we get

2 (L + W) = 28

Substituting the values of L and W

2 (2w - 1 + w) = 28

2 (3w - 1) = 28

Dividing both sides by 2

3w - 1 = 14

3w = 14 + 1

3w = 15

Dividing both sides by 3

w = 5

Therefore, the value of w is 5.
