Answer» Answer: (i) LENGTH = 2 m (II) Perimeter = 656 cm = 6.56 m (iii) Area = 25600 cm² = 2.56 m² Step-by-step explanation: (i) Breadth of the rectangle = 1.28 m = 128 cm Let the length of the rectangle be x Length = 128 + 72 = 200 cm = 2 m (ii) Perimeter = 2(l + b) = 2(128 + 200) = 2 × 328 = 656 cm = 6.56 m (iii) Length = 2 × 200 = 400 cm = 4 m Breadth = 128 cm = 1.28 m Area of the rectangle = l × b square UNITS = 128 × 200 = 25600 cm² = 2.56 m² I HOPE IT HELPS YOUMARK AS BRAINLIEST :) |
