Anmol has chart paper 90×40 cm, Abhishek has 50×70 cm. Which covers more area and by how much?
Step 1: Formula for area of a rectangle
Area = length × breadth.
Step 2: Area of Anmol’s chart
Length = \(90\) cm
Breadth = \(40\) cm
Area = \(90 \times 40 = 3600\ \text{cm}^2\)
Step 3: Area of Abhishek’s chart
Length = \(50\) cm
Breadth = \(70\) cm
Area = \(50 \times 70 = 3500\ \text{cm}^2\)
Step 4: Compare the areas
\(3600\ \text{cm}^2\) is greater than \(3500\ \text{cm}^2\).
Step 5: Find the difference
Difference = \(3600 - 3500 = 100\ \text{cm}^2\)
Conclusion: Anmol’s chart covers more area by \(100\ \text{cm}^2\).
