Answer:
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
