Answer 1

Step-by-step explanation:

ans.....- 700 msq......

Answer 2

Given:-

• Side = A = 40cm
• Side of Strip = a = 5cm

━━━━━━━━━━━━━━━

Need to find:-

• The area of the remaining sheet = ?
• The area of Strip = ?

━━━━━━━━━━━━━━━

Solution:-

The total area of the sheet with the Strip:-

= A × A

= 40 × 40 cm²

= 1600 cm²

━━━━━━━━━━━

Area of the Strip:-

= length × Breadth

= length of square sheet × 5 cm

= 40 × 5 cm²

= 200 cm²

Thus, Area of the Strip is $\red{\boxed{\bold{\large{ = 200{cm}^{2}}}}}$

━━━━━━━━━━━

Area of remaining sheet:-

= Area of the sheet with strip - Area of the strip

= 1600 cm² - 200 cm²

= 1400 cm²

Therefore, Area of the remaining sheet is $\red{\boxed{\bold{\large{ = 1400{cm}^{2}}}}}$
