Best answer
Right answer is (c) 6.67 cm

For explanation I would say: The length of the scale is determined by the formula, length of the scale = representative fraction x maximum length to be measured, that is, length of the scale = 1 ÷ 60 x 4 x 100 = 6.67 cm. Hence the length of the scale is 6.67 cm.
