Answer 2

Given :-

• Breadth of Rectangle = 8cm
• Perimeter of Rectangle = 64cm

To Find :-

• Length of Rectangle

Solution :-

➞ Perimeter of Rectangle = 2 ( L + B )

➞ 64 = 2 ( Length + 8 )

➞ 64 / 2 = Length + 8

➞ 32 = Length + 8

➞ 32 - 8 = Length

➞ 24cm = Length

________________

Verification :

⟾ Perimeter of Rectangle = 2 ( L + B )

⟾ Perimeter of Rectangle = 2 ( 24 + 8 )

⟾ Perimeter of Rectangle = 2 × 32

⟾ 64 = 64

Hence Verified

Thus, Length of Rectangle is 24cm
