Area of the Cardboard:
length × breadth
= 50 × 30
= 1500 cm²
Area of the picture:
= (50-2.5) × (30-2.5)
= 47.5 × 27.5
= 1306.25cm²
Area of the margin:
=Area of the Cardboard - Area of the Picture
=1500-1306.25
= 193.75 cm²
length × breadth
= 50 × 30
= 1500 cm²
Area of the picture:
= (50-2.5) × (30-2.5)
= 47.5 × 27.5
= 1306.25cm²
Area of the margin:
=Area of the Cardboard - Area of the Picture
