Well!

first let the length be 'l' and breadth be 'b'

so, perimeter = 2(l + b)

given that,
length is thrice the breadth
l = 3b

now, substitute it in the formula for perimeter !

44 = 2(3b + b)
44 = 8b
b = 44/8 = 11/4 cm

l = 3b = 11/4 × 3 = 33/4 cm

The answer would be A. 1 1/5

48/40 = 1 8/40

1 8/40 Simplify to 1 1/5

Hope this helps!

I believe it is 60-10=x because it says she purchased it with 60$ but recieved 10$ in change causing the amount we dont know to be a variable such as "x"
