sides are in the ratio begin mathsize 12px style 1 third space colon space 1 fourth space colon space 1 fifth end style
To make the ratio as integers, we need to multiply all fractions by LCM of 3,4 and 5, which is 60
 
Hence sides are in the ratio 20:15:12
 
if perimeter is 94 cm, largest side = 94×(20/47) = 40 cm
