Answer:

Answer 61

How many questions do you have? because I have to go soon.

Answer 62

oh if u have to go u can go ill just ask someone else

Answer 63

L = length
L = w + 7
2(w + 7) + 2w > 62
2w + 14 + 2w > 62
4w + 14 > 62
4w > 62 - 14
4w > 48
w > 48/4
w > 12 so the width is more than 12 mm

Answer 64

There. ok bye.

Have a nice day ;)
