In two similar triangles , the sides of the smaller triangle are 5cm , 7cm, 8cm .if the perimeter of larger triangle is 100cm, find the sides of larger triangle

The sides of the smaller triangle are 5cm , 7cm, 8cm .

The perimeter of smaller triangle = 5 + 7 + 8 = 20 cm

The perimeter of larger triangle is 100cm

We know ,

5 =

25 = x

Side of smaller triangle = 5cm

the side of larger triangle = 25 cm

5 * 5 = 25 so scale factor = 5

Multiply each side by 5 to get sides of larger triangle

5 * 5= 25 cm

7 * 5 = 35cm

8 * 5 = 40cm

The sides of the larger triangle are 25cm , 35cm, 40cm .

the answer is: the length is 5/6 yards.

give me a or a 5 star rating if this is correct!

step-by-step explanation:

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
