Question

Josh is building an enclosure with recycled cardboard for his collection of model cars. His design is as shown.


Josh needs a total length of 238 inches of cardboard for his project. What is the length of side AF in inches?

Answer 1

76

42

49

56

Answer 2

um, excuse me, in the design, isn't there a scale?

Answer 3

oh, I see

Answer 4

lol yea @HyperChemist

Answer 5

Every inch in the model is 7 inches, so...

Answer 6

now then, in the design it tells us that K L is 9 inches, however, we need to find Af, to find Af, we must subtract N M By Kl,

Answer 7

now then, show me, Nm-Kl, and then you multiply your answer by 7

Answer 8

that will give you Af in the model.

Answer 9

ummm idk @HyperChemist

Answer 10

what I did was divide the only number in the model, 56, by its similar number in the design, 8, once I divided it told me for every inch in the design, in the model it was going to be 7 inches, so to find af, we must subtract nm 2, minus kl 9.

Answer 11

please, tell me if your having any problems.

Answer 12

Answer 14

here you have to compute this ratio, first:
\(CD/ML= 56/8=...?\)
