Answer:
She should by 4 meters of material
Explanation:
1. First you need to add the 3 lengths of material the dress maker needs.
2. 88 cm + 189 cm + 80 cm = 357 cm
3. Next you need to convert the centimeters to meters
4. The conversion is 1 cm equals .01 meters
5. 357 x .01 = 3.57 meters
5. Since the shop only sells material in 1 meter lengths you must round
to the nearest whole number.
6. 3.57 rounded to the nearest whole number becomes 4.00
7. The answer is 4 meters
