You have a set of nested boxes whose lengths vary directly with their widths. One box is 2.5 in, wide and 5.5 in. long. A second box is 3 in. wide. How long is it?

A 1.36 in.
B. 6.6 in.
C 6.0 in
D. 1.01 in

B

Step-by-step explanation:

If you're looking for direct correlation, you're looking for a proportion for the second box. So you set the ratio of 2.5:5.5 up as a fraction. 2.5/5.5 and set it equal to the second box 3/x.

2.5     =      3

5.5             x

cross multiply

16.5=2.5x

and divide

16.5/2.5 and you get your answer

answer: bearing in mind that a rectangle has a perimeter of length + length + width + width.

step-by-step explanation:

p = perimeter

l = length

x=width

p = 2l + 2x

p = 2(l+x)     < ==== perimeter of the base of the box.

i think the answer is b
