Answer 2

Given :-

• Area of Square = Area of Rectangle
• Breadth of the Rectangle = 25cm
• Side of Square = 40cm

To Find :-

• Length of the Rectangle.

Solution :-

★ Area of Square ★

⇒ Area of Square = Side × Side

⇒ Area of Square = 40 × 40

⇒ Area of Square = 1600cm²

━━━━━━━━━━━━

★ According to the Question ★

⇛ Area of Square = Area of Rectangle

⇛ 1600 = Length × Breadth

⇛ 1600 = Length × 25

⇛ 1600/25 = Length

⇛ 64cm = Length

━━━━━━━━━━━━

Verification :-

⇛ Area of Square = Area of Rectangle

⇛ Side × Side = Length × Breadth

⇛ 40 × 40 = 64 × 25

⇛ 1600 = 1600

Hence, Verified

━━━━━━━━━━━━

∴ Length of Rectangle = 64cm ( c )

━━━━━━━━━━━━

★ Additional Info :

• Area of Square = Side x Side
• Area of Rectangle = Length × Breadth
• Perimeter of Rectangle = 2(Length + Breadth)
• Perimeter of Square = 4× Side
