Answer 1

s ≈ 11.13 in

General Formulas and Concepts:

Pre-Algebra

• Equality Properties

Geometry

Area of a Square Formula: A = s²

• s is a side length

Explanation:

Step 1: Define

Identify

A = 124 in²

Step 2: Solve for s

1. Substitute in variables [Area of a Square Formula]: 124 in² = s²
2. [Equality Property] Square root both sides: s = 2√31 in
3. Approximate: s = 11.1355 in
