Tasha's bedroom is shaped like a square. The room has an area of 169 ft?.
What is the length of one side of Tasha's bedroom?

  13 ft

Step-by-step explanation:

Since you have memorized the squares of numbers up to 20, you know that ...

  13² = 169

The area of a square is the square of its side length, so one side of Tasha's bedroom is 13 feet.

If you haven't memorized those squares, you can use your calculator to find the square root of 169.

The formula for area of a square is ...

  A = s²

Taking square roots, we have ...

  s = √A

  s = √169 = 13 . . . . feet
