raden · Answer

a). length (l) = w + 8 (known)

b). perimeter > 60
2w + 2l > 60
because l = w + 8, so
2w + 2(w+8) > 60
2w + 2w + 16 > 60
4w + 16 > 60

c). 4w + 16 > 60
first, subtract by 16 on both sides, get
4w + 16 - 16 > 60 - 16
4w > 44
then divided by 4 on both sides, get
4w/4 > 44/4
w > 11

because w > 11 then
length would be more than :
length (l) = w + 8 = 19
length (l) > 19
