First, we need to translate 1 dm into cm.And as we know, 1 dm is 10 cm.
This means that the width is 10 cm less than the length. Now we find the width, subtract 10 from 17 and get 7. Now we can find the area (multiply the length by the width) and the perimeter (add all the sides). Perimeter: 17 + 17 + 7 + 7 = 48. Area: 17 × 7 = 119.
