To find the cost of three meters of wire, we first need to determine the cost per meter of wire. Given that two meters of wire cost ninety pence, we can calculate the cost per meter by dividing the total cost by the number of meters: 90 pence / 2 meters = 45 pence per meter. Therefore, three meters of wire would cost 3 meters * 45 pence/meter = 135 pence.
