The details of the dimensions of the fabric needed to make the school tie are;

The length of the required fabric = 135 cm

The width of the fabric for the tie = 9 cm

The width of a roll of fabric when sold = 90 mm = 9 cm

The cost of the fabric per meter = £3.55

The width of the roll of fabric = The width of the  fabric material required to make a tie

The cost of 1 m (100 cm) of fabric = £3.55

Therefore;

The cost of the 135 cm of the fabric required for the tie, c, is found as follows;

c = £3.55 × 135/100 = £4.7925

The cost of the fabric required to make one tie giving the answer to two decimal place, c ≈ £4.79
