Two triangles are similar. The lengths of corresponding sides are in the ratio 3:5. If the smaller triangle has a perimeter of 24 cm, find the perimeter of the larger triangle.

Let the scale factor between the triangles be 

𝑘=5/3

Perimeter of the larger triangle =𝑘 × Perimeter of the smaller triangle

Perimeter of the larger triangle 

=5/3×24

Perimeter of the larger triangle 

=40 cm

Answer: Perimeter of the larger triangle is 40 cm.
