How do I measure an irregular shape?

Break the shape into regular components (rectangles, triangles, etc.), calculate each area separately, then add them together.

What is the difference between area and perimeter?

Area measures the space inside a 2D shape (in square units). Perimeter measures the distance around its boundary (in linear units).

1 m² = 10.764 ft² = 10,000 cm². To convert, multiply by the conversion factor between the two unit systems squared.
