Answer:
First one.
Step-by-step explanation:
0.3/3=0.1 ==> 0.1$ per meter
0.77/7 ==> 0.11$ per meter
The first option is cheaper, therefore better to buy if you agree with "the cheaper. the better".
I say the answer is A, correct me if I'm wrong.
Perimeter of square = 4 x l
so ATC 4 x l = 240
= 240/40= l
so 60 = l
the answer is 60 inches.
