Question

Can you help me.the lengths of the sides of a triangle are in the extended ratio 3:10:12. The perimeter is 400cm. What is the length of the longest side in centimeters.
Steve
Suppose the sides were exactly 3,10,12. The perimeter would be 25.

But, the actual perimeter is 400 = 16*25

So, the sides are 16*3,16*10,16*12 = 48,160,192

The perimeter of a scalene triangle is 14.5 cm. The longest side is twice that of the shortest side. Which equation can be used to find the side lengths if the longest side measures 6.2 cm?
