Question

the sides of a triangle are in the ratio 3:5:7 and it's perimeter is 45 cm . What are the lengths of the sides?​

Answer 1

Step-by-step explanation:

Let the measures of the triangle be 3x, 5x, and 7x.

Perimeter of the triangle = 45cm

Length of the triangle sides,

3x + 5x + 7x = 45

15x = 45

x = 45/15

x=3

Hence the measures of the triangles are (3x3,5x3 and 7x3) 9,15 and 21.
