A carpenter was told to make a rectangular desk with top of dimension 50cm by 40cm. The carpenter actually made the desk 60cm by 35cm. (a) Calculate the percentage error in the (i) length and the breadth ; (ii) area of the table top. (b) Find the product of the two errors in a(i).
Explanation
Error in length = 60cm - 50cm = 10cm Error in breadth = 40cm - 35cm = 5cm (i) % error in length = % error in breadth = (ii) Area of the actual table = Area of the table in error = Error in area = % error in area = (b) Product of the error in length and in breadth =
