Question

The sides of a triangle are in the ratio 5:3:4. If perimeter of the triangle is 180cm find the area of the triangle. ​

Answer 1

Step-by-step explanation:

P = a + b + c

180 = 12x

x = 15

5x = 75

3x = 45

4x = 60

Step-by-step explanation:

Let's the sides of traiangles are in the ratio 5x,3x,4x

So, perimeter of triangle = 180cm

Therefore 5x+3x+4x=180

12x=180

x=180/12

x=5

So the 5x is 5x5=25

3x=3x5=15

4x=4x5=20
