Step-by-step explanation:

Answer 2

Answer:

15cm

Step-by-step explanation:

Since BC is like ST but smaller, we have to find the length of BC then find the proportion for ST.

Length of BC = 36.8 - 4.4 - 13.2 - 2.2 - 11

                      = 6

Scale = $\frac{33}{13.2}$

Length of ST = $\frac{33}{13.2}$ × 6

                      = 15
