I'm really confused on how to do this and it's due reay soon, so 1-4

1) No. A closet is an area. The 1st closet area = 3 x 5 = 15 & the area of the 2nd closet is 6 x 10 =60 . Then it's 4 times larger

2) find both perimeters: 1st = 30 feet & 2nd = 120 ft  

3) find both area 1st = 15 ft² & 2nd = 60 ft²

4) Since the 2nd carpet is 4 times larger than the old, then the cost of the new carpet will be 4* 42= $168

Aand b is what i think
