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



What is the length of side BC in inches?
a. 14
b. 42
c. 49
d. 63

Answer 1

the correct answer is 63 because they are multiplying the length of each side by 7.

Answer 2

Answer: Option 'd' is correct.

Explanation:

Since we have given two figures:

John's design is similar to Josh's project.

ML = 8 inches

CD = 56 inches

KL = 9 inches

We need to find value of 'BC'.

So, there ratio would be :

`(ML)/(CD)=(KL)/(BC)\\\\(8)/(56)=(9)/(BC)\\\\(1)/(7)=(9)/(BC)\\\\BC=9* 7\\\\BC=63\ inches`

Hence, Option 'd' is correct.
