3x+4x+5x = 60
12x = 60
x= 60/12
x = 5
12x = 60
x= 60/12
x = 5

Given,
perimeter of the triangle = 60cm
ratio of sides of the triangle = 3:4:5
length of the first side = 3/12×60
= 15cm
length of the second side=4/12×60
=20cm
length of the third side =5/12×60 =25 cm
area of the triangle = l×b×h
=15×20×25 = 7500
perimeter of the triangle = 60cm
ratio of sides of the triangle = 3:4:5
length of the first side = 3/12×60
= 15cm
length of the second side=4/12×60
=20cm
length of the third side =5/12×60 =25 cm
area of the triangle = l×b×h
=15×20×25 = 7500
