Understanding Perimeter and Area
To appreciate the value of perimeter and area worksheets, it’s crucial to grasp the definitions of perimeter and area.
What is Perimeter?
Perimeter refers to the total distance around the edge of a two-dimensional shape. It is calculated by adding the lengths of all the sides of the shape. For common geometric figures, the formulas for perimeter are as follows:
- Rectangle: P = 2(l + w)
(where l is the length and w is the width)
- Square: P = 4s
(where s is the length of a side)
- Triangle: P = a + b + c
(where a, b, and c are the lengths of the triangle's sides)
What is Area?
Area measures the space contained within a two-dimensional shape. It is expressed in square units. The formulas for calculating the area of common shapes are:
- Rectangle: A = l × w
- Square: A = s²
- Triangle: A = (b × h) / 2
(where b is the base and h is the height)
