Question

each side of a triangle increased by 10 cm. if the ratio of the premeter of a new triangle and a given triangle is 5:4. find the peremeter of a given triangle ​

Answer 1

Answer:

120

Step-by-step explanation:

Let the perimeter be x + y + z

new perimeter is x + y +z + 30

x + y + z + 30/ x + y + z = 5/4

4(x + y + z+ 30) = 5(x + y + z)

4x + 4y + 4z + 120 = 5x + 5y + 5z

120 = x + y + z

hence the perimeter of the given triangle is 120
