Answer:
The area of the remaining chart paper is 6m² and the area of cut out strip is 6m².
Step-by-step explanation:
The length of the chart paper= 4m
The width of the chart paper= 3m
After cutting, the length of the chart paper= (4-1)m= 3m
After cutting, the width of the chart paper= (3-1)m= 2m
Area of remaining chart paper= (3×2)m²= 6m².
Area of strip={(4×3)-6}m²= 6m².
