Answer:

BC = 28

Step-by-step explanation:

Since the triangles are similar then the ratios of corresponding sides are in proportion, that is

$\frac{BC}{EF}$ = $\frac{AB}{DE}$ ( substitute values )

$\frac{BC}{7}$ = $\frac{16}{4}$ = 4 ( multiply both sides by 7 to clear the fraction )

BC = 4 × 7 = 28
