Question

the sides of triangle are in ratio5:7:8 if the perimeter of the triangle is 100 cm find the length of the side of the triangle ​

Answer 1

Step-by-step explanation:

1. Let the first side = 5x

2. Let the second side =7x

The third side = 8x

The perimeter = sum of all side

100 = 5x + 7x + 8x

100= 20x

100/20 = x

5 = x

Therefore first side = 25

Second side = 35

Third side = 40

Here is your answer

Answer 2

ANSWER:

25cm, 35cm and 40cm


STEP BY STEP EXPLANATION:

The ratio of the sides of the triangle is 5:7:8
Let the sides be 5x,7x and 8x respectively

We know, perimeter of a triangle=side+side+side
Perimeter given=100cm

ATP-
5x+7x+8x=100
=> 20x=100
=> x=100/20
=> x=5

Replacing values of x, we get the sides as 25cm, 35cm and 40cm
