Q2 of 42 Page 210

The perimeters of two similar triangles are 30 cm and 20 cm respectively. If one side of the first triangle is 12 cm, determine the corresponding side of the second triangle.

Given, perimeters of two similar triangles are 30cm and 20cm


And one side of the triangle is 12cm.


Need to find out the side of the second triangle.


⇒ since, the triangle are similar


⇒ =


⇒


⇒ x =


⇒ x = 8cm.


Hence, the corresponding side of the second triangle is 8cm
