A square has a diagonal length 18 in. What is the side length of the square?
Elenna [48]

Answer:

9\sqrt{2} inches

or

12.728 inches

Step-by-step explanation:

Use Phytagorean Theorem

a^{2} +b^{2} =c^{2}

Since both all sides of a square are equal, this means that a^{2} and b^{2} are equal.

So that leaves us with:

a^{2} +a^{2} = 18^{2}

Simplify

2a^{2} = 324

Divide both sides by 2

\frac{2a^{2} }{2} =\frac{324}{2}

Simplify

a^{2} = 162

Find the square root of both sides

\sqrt{a^{2} } =\sqrt{162}

a = 9\sqrt{2}

(or if you want the decimal, rounded to the 3rd decimal place: 12.728)
