Question

The ratio of the measures of the size of a triangle is 6:7:9 and it's perimeter is 77 cm find the measure of each side of the triangle

Answer 1

21 CM

24.5 cm

31.5 cm

Explanation:

Measure of each side = (ratio of each side / sum of ratios) x perimeter

Sum of ratios = 6 + 7 + 9 = 22

6/22 x 77 = 21 cm

7/22 x 77 = 24.5 cm

9/22 x 77 = 31.5 cm
