Explanation & Answer

Thank you for the opportunity to help you with your question!

The perimeter of a rectangle of length l and width b is given by the formula

P= 2(l+b)

Here P = 220 cm and b= 53 cm

So

220= 2(l+ 53)

l + 53= 220/2

l +53= 110

l=110-53= 57 cm

Length of the rectangle is 57 cm.

Please let me know if you need any clarification. I'm always happy to answer your questions.
