Perimeter question (10th grade geometry)?

Question

hey :)

I don't know why this is difficult for me but w/e. Here's the question from my homework:

The area of an 11 -cm wide rectangle is 176 cm squared. What is it's length?

Answer 1

176/11= 16 so

16+16+11+11= 54

perimeter= 54 cm

Answer 2

Area = Length x Width

176 = Length x 11     Divide both sides by 11

176/11 = Length

16 = Length

Check the answer:  11 x 16 = 176

Answer 3

11 times what = 176....
