Area vs. Perimeter: What's the Difference?

Edited by Sumera Saeed || By Sawaira Riaz || Published on November 27, 2023
Area measures the space within a shape, while perimeter is the total length of a shape's boundaries.

Key Differences

Area refers to the space contained within a two-dimensional shape, measured in square units. It represents the extent of a surface. Perimeter, on the other hand, is the total distance around the edges of a shape. It is a linear measurement and indicates the boundary length.

Calculating the area involves multiplying length by width for rectangles, or using more complex formulas for other shapes. Area quantifies the size of the surface. While, to find the perimeter, one adds up the lengths of all sides of the shape. It measures the distance around a shape, not inside it.

The area is crucial in fields like architecture and interior design for space utilization. It helps in understanding how much space is available. However, the perimeter is significant in fencing or bordering a property, as it determines how much material is needed to enclose an area.

The concept of area is used in calculating land size, flooring, or painting required for a surface. It's about covering a space. Whereas, perimeter calculations are essential for tasks like setting up fences or borders. It deals with the length needed to surround a space.

Different shapes have different area formulas, like circles use πr², emphasizing the shape's dimensions. The formula for perimeter depends on adding side lengths, focusing on the linear dimensions of the shape's boundary.
