Question

The length of a rectangle is 6 units longer that the width , w.

Answer 1

No B

lets say W is 5

C is saying 4x5+6 right?

so all 4 side are 5 and plus a random six

W is only equal to 2 sides so C and D are gone

A. 2 x 5 + 6 is saying
2 sides are 5 + 6 and then a missing side

but B is 2 x 5 + 12
B could also say 2 x 5 + 2 x 6
2 sides are 5 and then 6 side are 5

Your answer is B
