Answer:
What's 2.54 cm in inches?
To convert cm to inches, divide your cm figure by 2.54 or multiply it by 0.3937. As an example, let's say you have a piece of wood measuring 50cm and you want to convert it into inches. To get your answer, divide your cm figure by 2.54. So, 50 ÷ 2.54 = 19.685 inches.

Step-by-step explanation:
The length and breadth(width) of the pool are
Let
From the question, we can build the following relationships
subtracting to eliminate 
(we do not even need it!)
we can also build another relationship from the question. Since the area of the strip equals the area of the pool:
We have two unknowns, 
and 
. Eliminate
If we solve the quadratic equation for , we get
and

To solve for the missing steps, let's rewrite first the problem.
Given:
In a plane, line m is perpendicular to line t or m⟂t
line n is perpendicular to line t or n⟂t
Required:
Prove that line m and n are parallel lines
Solution:
We know that line t is the transversal of the lines m and n.
With reference to the figure above,
∠ 2 and ∠ 6 are right angles by definition of <u>perpendicular lines</u>. This states that if two lines are perpendicular with each other, they intersect at right angles.
So ∠ 2 ≅ ∠ 6. Since <u>corresponding</u> angles are congruent.
Therefore, line m and line n are parallel lines.
