Question

The area of a triangle is 150 cm2 and its sides are in the ratio 3 : 4 : 5. What is its perimeter?​

Answer 1

Answer: let the three sides be 3x 4x and 5x

Step-by-step explanation:

base could be =3x

and height as =4x

the area of triangle = 1/2*b*h

                                =1/2*3x*4x

                                =6x=150

                               x=150/6

                                x=25cm

perimeter = sum of all sides

2x+3x+5x=2*25+3*25+5*25=50+75+125= 250cm
