⬜ Square Area Calculator

Calculate area, perimeter, and diagonal

Square Formulas

Area

Area = Side × Side = Side²

Example: 10² = 100 sq units

Perimeter

Perimeter = 4 × Side

Example: 4 × 10 = 40 units

Diagonal

Diagonal = Side × √2 ≈ Side × 1.414

Example: 10 × 1.414 ≈ 14.14 units

Frequently Asked Questions

What makes a square different from a rectangle?

A square is a special rectangle where all four sides are equal. Rectangle: length ≠ width. Square: all sides equal.

Why is the area formula Side²?

Area = length × width. For a square, length = width = side, so Area = side × side = side². Example: 5 × 5 = 5² = 25.

How do I find the diagonal of a square?

Use the Pythagorean theorem: diagonal² = side² + side² = 2×side². So diagonal = side × √2 ≈ side × 1.414.

What if I only know the diagonal?

Work backwards: side = diagonal ÷ √2 ≈ diagonal ÷ 1.414. Then calculate area = side².

How many square feet in a 10x10 room?

10 ft × 10 ft = 100 square feet. This is a common size for small bedrooms or home offices.
