Question

Cory is building an enclosure with recycled cardboard for her collection of model cars. Her design is a shown below.

Answer 1

The 2 figures are similar so corresponding sides are in smae ratio

Note that similar sides CD and ML are in ratio 40:8 which is 5 : 1.

So EF = 5 * NH = 5*5 = 25 answer

Its choice B

Answer 2

Answer:

B.25

Explanation:

The figures are similar.  This means that corresponding sides have the same ratio.

This helps us set up a proportion.

We know that ML corresponds with DC, which gives us the ratio

8/40

EF will correspond with NH; this gives us the ratio

5/x

The proportion is then

8/40 = 5/x

Cross multiplying, we have

8(x) = 40(5)

8x = 200

Divide both sides by 8:

8x/8 = 200/8

x = 25
