Question

the sides of a triangular plot are in the ratio 2:3:4 and it's perimeter is 450m. find it's area​

Answer 1

let sides be X

2x+3x+4x= 450

9x=450

x=450/9

x=50

2*50=100=a

3*50=150=b

4*50=200=c

by herons formula

S = a+b+C/2

S= 100+150+200/2

S= 450/2

S= 225

√225(225-100)(225-150)(225-300) { every thing is in under root}

√225*125*75*(-75)

√225*125*(-5625)

√28125*(-5625)

√-158203125

12577.88 is the answer it may be wrong
