Question 15.
What is different about perimeter and area? Explain.
Answer:
Perimeter is the distance around the outside of a shape.
Area measures the space inside a shape.
Learn how to calculate perimeter and area for various shapes.
Explanation:
Area- Area is defined as space/region occupied by a two-dimensional flat object.
It is measured in square units.
Consider a square having side ‘a’ then the area of the square is given by a2.
Perimeter- Perimeter is defined as the length of boundaries of a closed figure.
For example, a square having side length equal to ‘a,’ then the perimeter will be the sum of all its four sides, i.e. ‘4a.’
The measurement of the Perimeter is in the unit.
