What is the value of w? 5 units 7 units 14 units 15 units

w = 5 units.

Step-by-step explanation:

The question is as following:

See the attached figure.

The perimeter of the rectangle is 28 units, What is the value of W?

5 units

7 units

14 units

15 units

================================================

Solution:

perimeter= 2(Length + Width)

From the attached figure ⇒ length = 2w-1  & width = W

∴ 2(2W - 1 + W) = 28

Solve for w

∴ 2(3W-1) = 28

∴ 6W - 2 = 28

∴ 6w = 30

∴ w = 5 units
