Answer:
6 cm,12 cm,8 cm
Step-by-step explanation:
add the perimeter of the first triangle to get 65
then divide 65 by 26 to get 2.5
then divide all the side lengths by 2.5
15/2.5=6
20/2.5=8
30/2.5=12
The lengths of the sides of a similar triangle that has a perimeter of 26 cm are 6 cm, 8 cm, and 12 cm and this can be determined by using the given data.
Given :
The lengths of the sides of a triangle are 15 cm, 20 cm, 30 cm.
The following steps can be used in order to determine the lengths of the sides of a similar triangle that has a perimeter of 26 cm:
Step 1 - The formula of the perimeter of the triangle is given below:
[tex]\rm P = a + b + c[/tex]
where a, b, and c are the length of the sides of the triangle.
Step 2 - Now, determine the perimeter of the triangle whose sides are 15 cm, 20 cm, 30 cm.
P' = 15 + 20 + 30
P' = 65 cm
Step 3 - Now, divide both the perimeters of the triangles, that is:
[tex]=\dfrac{65}{26}[/tex]
= 2.5
Step 4 - So, the side length of the sides of a similar triangle is given below:
[tex]\rm \dfrac{15}{2.5} = 6\;cm[/tex]
[tex]\rm \dfrac{20}{2.5}=8 \;cm[/tex]
[tex]\rm \dfrac{30}{2.5}=12\;cm[/tex]
