Answer:

perimeter of Δ GIH = 6 units

Step-by-step explanation:

given Δ EIF and Δ GIH are similar , then the ratios of corresponding sides are in proportion , that is

[tex]\frac{IH}{IF}[/tex] = [tex]\frac{2}{6}[/tex] = [tex]\frac{1}{3}[/tex]

That is the sides of Δ GIH are [tex]\frac{1}{3}[/tex] the corresponding sides of Δ EIF

Since the sides are in proportion, then the perimeters are in the same proportion

perimeter of Δ EIF = 5 + 6 + 7 = 18 units , then

perimeter of Δ GIH = [tex]\frac{1}{3}[/tex] × 18 = 6 units
