Question

The sides of the triangular plot are in the ratio 3:5:4 and its semi perimeter is
450m. Find its area

Answer 1

Answer:

let , ratio as x

given, 3x:5x:4x sides

and , perimeter = 450

than ,

3x+4x +5x = 450. 3x = 37.5× 3= 112.5

12x = 450. 4x = 150

x = 450/12. 5x = 187.5

x = 37.5

area, √s(s-a)(s-b) (s - c )

s = 450/2= 225

than, √225(225-112.5) ( 225- 150) ( 225 - 187.5)

solve.....
