Two triangles are similar. The length of a side of the first triangles is 1.5 times as long as the length of the corresponding side of the other, then which of the following is not true?
The perimeter of the larger triangle will be 1.5cm, if the perimeter of the smaller one is 10cm
If the area of the smaller triangle is 6cm2, then the area of the larger triangle will be 9cm2
If a side of the larger triangle is 9 cm long, then the corresponding side of the smaller triangle will be 6 cm long
If the sum of the lengths of the two sides of the larger triangle is 9 cm2, then the sum of the lengths of the two corresponding sides of the smaller triangle is 6 cms
