Question

the perimeters of two similar triangles are 60cm and 40 cm respectively. if one side of first triangle is 12 cm then determine corresponding side of second triangle​

Answer 1

Answer:

A=24cm

Step-by-step explanation:

Let the sides of one triangle be a,b,c

Let the sides of another triangle be A,B,C

as the triangle are similar means that

a = b= c =K

A B C

here K is constant

a=KA

b=KB

c=KC

Ratio of perimeters is a+b+c = 40

A+B+C 60

K=0.5

According to the question,

12=0.5A

A=24 cm
