Answer:

x = 4.5 m ⇒ A

Step-by-step explanation:

The sides of similar triangles are proportion, that means the ratio between the corresponding sides are equal

In the given figure

∵ The two triangles are similar

2 m and x are corresponding sides

4 m and 9 m are corresponding sides

∴ [tex]\frac{2}{x}[/tex] = [tex]\frac{4}{9}[/tex]

→ By using cross multiplication

x × 4 = 2 × 9

∴ 4x = 18

→ Divide both sides by 4 to find x

∵ [tex]\frac{4x}{4}[/tex] = [tex]\frac{18}{4}[/tex]

x = 4.5 m
