उत्तर
The sides of a triangle are in the ratio 12 : 14 : 25 and its perimeter is 25.5 cm. The largest side of the triangle is 12.5 cm.
Explanation:
Let the common factor be k.
Sum of ratio parts = 12 + 14 + 25 = 51.
So `k = "Perimeter"/51`
= `(25.5)/51`
= 0.5
The largest side = 25 × k
= 25 × 0.5
= 12.5 cm
