A) 3 cm
B) 4 cm
C) 5 cm
D) 6 cm
Correct Answer: C
Solution :
The perimeter of a triangle = 30 cm Area \[=30\,\,\text{c}{{\text{m}}^{2}}\] We know that, \[{{5}^{2}}+{{12}^{2}}={{13}^{2}}\] \[\therefore \]The triangle is right angled Now, Area \[=\frac{1}{2}\times 5\times 12=30\,\,\text{c}{{\text{m}}^{2}}\] And Perimeter \[=5+12+13=30\] Hence, the smallest side is 5 cm.You need to login to perform this action.
