The lengths of the sides of a triangle are in the extended ratio 5 : 7 : 10. The perimeter of the triangle is 110 cm. What are the lengths of the sides?
5 : 7 :10 indicates that there are 22 equal parts.....so
5 / 22 of 110 = 25
7 / 22 of 110 = 35 and
10 / 22 of 110 = 50
Check that 25 + 35 + 50 = 110
