Download Solution PDFGiven:
The length and breadth of a rectangle are increased by 8% and 5%, respectively.
Concept used:
Final percentage change after two successive increments of A% and B% = \((A + B + {AB \over 100})\%\)
Calculation:
Final percentage increment in area = \(8 + 5 + \frac {8 \times 5}{100}\) = 13.4%
∴ The area will increase by 13.4%.
