Answer 1

Answer:

Given :

• Area of a triangle = 150 cm².

• Ratio of its sides = 3 : 4 : 5.

To find :

• the perimeter of the triangle.

Solution :

• Let the first side be 3x.

• Let the second side be 4x

• Let the third side be 5x.

Semi - perimeter =[tex]\dfrac{3x + 4x + 5x}{2 }[/tex]

• Semi - perimeter = 6x.

• We know that,

area of a triangle = √s(s-a)(s-b)(s-c)

According to the question :

• Area = 150 sq.cm.

150 = √6x(6x-3x)(6x-4x)(6x-5x)

150 = √6x(3x)(2x)(x)

x = 5

• Perimeter = a + b + c

• Perimeter = ( 15 + 20 + 25 ) cm.

• Perimeter = 60 cm.

Answer :

• So the perimeter of the triangle = 60 cm
