First, convert the dimensions of the sheet from meters to centimeters: a 2m by 4m sheet is 200cm by 400cm. The area of the sheet is 200cm x 400cm = 80,000 cm². The area of one street sign, which is 20cm high and 80cm wide, is 20cm x 80cm = 1,600 cm². Therefore, the number of street signs that can be made is 80,000 cm² ÷ 1,600 cm² = 50 signs.
