Imagine you want to build a fence around your garden - that's perimeter! If you want to plant grass inside the garden - that's area!
Simple Difference:
Perimeter: Distance around a shape (fencing)
Area: Space inside a shape (carpeting)
Perimeter = Total boundary length
Area = Total surface covered
Football Field:
Perimeter: Running track around the field
Area: Grass surface for playing
Room in House:
Perimeter: Length of skirting boards
Area: Space for carpet or tiles
Farm Land:
Perimeter: Fence around the farm
Area: Land for growing crops
Rectangle:
Perimeter = 2 × (Length + Width)
Area = Length × Width
Like a notebook or door
Square:
Perimeter = 4 × Side
Area = Side × Side
Like a chess board square
Circle:
Perimeter (Circumference) = 2πr
Area = πr²
Like a pizza or wheel
In this chapter, we will learn:
