Hello!

Here is the answer for your question!

Question:- The perimeter of a triangle is 300 m , if its sides are in the ratio 3 : 5 : 7 . Find the longest side.

------------------------------------------------------------------

Answer:-

Given:

  • Perimeter of triangle = 300m
  • Ratio of sides = 3 : 5 : 7
  • Perimeter of triangle = sum of lengths of three sides

From the information given;

= 3x + 5x + 7x = 300

15x = 300

x = 20

From the ratios longest side = 7x = 7×20 = 140cm

Length of longest side of the triangle is 140cm
