Question

12. The ratios of the side lengths of a triangle are 7:9:12. The perimeter is 56. What are the lengths of the sides? ​

Answer 1

7+9+12 = 28

doubling each side makes them 14 + 18 + 24 which equals 56

Explanation:

Answer 2

Explanation:

here's your solution

==> ratio of sides of traingle are given = 7:9:12

==> perimeter of traingle = 56

==> let the ratio be X

==> now , 7x + 9x + 12x = 56

==> 28x = 56

==> x = 56/28

==> x = 2

... length of sides = 7x = 14

.....9x = 18

12x = 24

. length of. sides = 14 ,18 ,.24
