Explanation

وہ حروف یا الفاظ جو کسی لفظ کے بعد لگائے جائیں اور اس کے معنی میں تبدیلی پیدا کریں، وہ لاحقے کہلاتے ہیں۔

لاحقہ وہ لفظ ہوتا ہے جو کسی بنیادی لفظ کے آخر میں لگ کر اس کے معنی یا نوعیت کو بدل دیتا ہے، جیسے "پڑھنا" سے "پڑھناہوا"۔

Explanation

L = length, W = width

Perimeter = 2(L + W) = 34 cm

If length increases by 2.5 cm:

New perimeter = 2(L + 2.5 + W)

= 2L + 5 + 2W

= 2(L + W) + 5

= 34 + 5

= 39 cm

Difference in perimeter = 39 - 34 = 5 cm
