The two sides of a triangle having perimeter 10 m are \(2\frac{1}{2}\) m and \(3\frac{1}{2}\) m.What is the ratio of the length of the three sides of triangles?

Answer»

Perimeter of triangle = 10 m

First side = \(3\frac{1}{2}\) m = \(\frac{5}{2}\) m

Second side = \(3\frac{1}{2}\) m = \(\frac{7}{2}\) m

Third side = 4 m Ratio of three sides of a triangle

\(=\frac{5}{2}:\frac{7}{2}:4=5:7:8\)
