A) \[18\,\,cm\]
B) \[48\,\,cm\]
C) \[24\,\,cm\]
D) \[36\,\,cm\]
Correct Answer: D
Solution :
Ratio of sides of a triangle is\[3:4:5\] The longest side \[=15\,\,cm=5\] units \[\therefore \]\[1\]unit\[=\frac{15}{5}cm=3\,\,cm\] Hence, \[3\,\,units=9\,\,cm\] and \[4\,\,units=12\,\,cm\] Therefore, perimeter of the triangle \[=(9+12+15)cm\] \[=36\,\,cm\]You need to login to perform this action.
