Question

Two similar figures have sides in the ratio of 2:3. If a side of the smaller triangle has a length of 7, what is the length of the corresponding side of the other triangle?

a.4 2/3
b.10 1/2
c.14
d.21

Answer 1

---------------- B) 10 1/2--------------------------------------

Answer 2

Lengths of corresponding sides of similar polygons are in proportion.

That means that 2 is to 3 as 7 is to x where x is the length of the side of the other

triangle.

2/3= 7/x

2x = 21

x = 21/2 = 10 1/2

Answer: b) 10 1/2
