Error in length = 60cm - 50cm = 10cm Error in breadth = 40cm - 35cm = 5cm (i) % error in length = \(\frac{10}{50} \times 100% = 20%\) % error in breadth = \(\frac{5}{40} \times 100% = 12.5%\) (ii) Area of the actual table = \(50cm \times 40cm = 2000cm^{2}\) Area of the table in error = \(60cm \times 35cm = 2100cm^{2}\) Error in area = \(2100cm^{2} - 2000cm^{2} = 100cm^{2}\) % error in area = \(\frac{100}{2000} \times 100% = 5%\) (b) Product of the error in length and in breadth = \(20 \times 12.5 = 250%\)
