The perimeter of the triangle is 96 cm and the lengths of the sides are in relation to 7:13:12

The perimeter of the triangle is 96 cm and the lengths of the sides are in relation to 7:13:12. Find the length of the sides of the triangle.

Given: perimeter – 96 cm, aspect ratio – 7: 13: 12

Find: all sides of the triangle.

First you need to find out how many parts are in the triangle, for this we add all the ratio numbers.

7 + 13 + 12 = 32

We have 32 parts in total. Now we need to find out how many cm are in one part.

96/32 = 3 (cm)

Now, using multiplication, we find each side.

7 * 3 = 21 (cm)

13 * 3 = 39 (cm)

12 * 3 = 36 (cm)

Answer: 21 cm, 39 cm, 36 cm.
