The perimeter of the rectangle is 28 units,
what is the value of x?
5 units
7 units
14 units
15 units

Answer with Step-by-step explanation:

Perimeter of rectangle is given by:

Perimeter= 2(Length+width)

Here, Length= 2w-1

Width= w

and Perimeter= 28 units

So, 28= 2(2w-1+w)

28= 2(3w-1)

28= 6w-2

6w= 28+2

i.e. 6w= 30

Dividing both sides by 6, we get

w= 5

Hence, Value of w is:

5 units

this doesn't make sense lol
