The lengths of the sides of a triangle are in the extended ratio 1: 2: 5. the perimeter of the triangle is 32 ft. the length of the longest side is?

Given that the extended ratio of the lengths of the triangle is given by 1:2:5 and the perimeter is 32ft, the actual length will be as follows:
1+2+5=8
1/8*32=4 ft
2/8*32=8 ft
5/8*32=20 ft
Therefore we conclude that the longest side is 20 ft
