25. The sides of a
triangle are in the ratio of 1/2:1/3:1/4. If its perimeter is 52 cm, the length
of the smallest side is :
(A) 9 cm (B) 10 cm
(C) 11 cm (D) 12 cm
Answer: D
Explanation:
Sides of a triangle are in the ratio of a:b:c = 1/2:1/3:1/4
= 12/2 : 12/3 : 12/4
= 6:4:3
Let the lengths of three sides of the triangle be 6x, 4x, 3x
Perimeter of the triangle = a+b+c ⇒ 52 cm = 6x +
4x + 3x
x = 52/13 = 4 cm
length of the smallest side = 3x = 3 x 4 = 12 cm
