Find the area and perimeter of the following objects. Use a scale or measuring tape to find the length and the breadth of each of the objects. [Table with: Cover of the Notebook, Newspaper, Blackboard, Ludo board, and two blank entries]
For each object, measure Length and Breadth using a scale or measuring tape.
Formula: Area = Length × Breadth Perimeter = 2 × (Length + Breadth)
Example (Notebook cover 25 cm × 18 cm): Area = 25 cm × 18 cm = 450 sq cm Perimeter = 2 × (25 cm + 18 cm) = cm = 86 cm
Record all measured and calculated values in the table.
Explanation
The chapter provides a practical activity where students measure real objects. This reinforces the application of area and perimeter formulas to everyday items. Students fill in the table with measured dimensions and calculated values.
Solution Steps
Step 1: Measure length of each object
Step 2: Measure breadth of each object
Step 3: Calculate Area = Length × Breadth
Step 4: Calculate Perimeter = 2 × (Length + Breadth)
Step 5: Record all values in the table
