Question

The areas of two similar triangles are 18 cm2 and 8 cm2. One of the sides of the first triangle is 4.5 cm. What is the length of the corresponding side of the other triangle?

Answer 1

Answer:9

Step-by-step explanation:

(Area of Large triangle/Area of smaller triangle)=(corresponding side of larger triangle/corresponding side of smaller)^2

So,

(18/8)=(4.5/x)^2

(4.5/2)=(20.25/x^2)

By canceling 4.5 and 20.25, we get,

(1/2)=(4.5/x)

By cross multiplication. We get,

x=9cm
