Question

Q1. The three sides of a triangle are in the ratio 2 : 3 : 4 and the perimeter 225 m. Find its area.

Answer 1

Answer: Length of one side =2x

Length of second side =3x

Length of third side =4x

Perimeter of triangle=225m

ATQ

Perimeter of triangle =side 1+side2+side3

225=2x+3x+4x

225=9X

225/9=X

25=X

X=25

LENGTH of one side =2x=25*2=50

Second side =3x=25*3=75

Third side =4x=25*4=100

Now find the area of triangle=

.

S =perimeter of triangle /2 = 225/2 =112.5

Answer 2

Step-by-step explanation:

2x+3x+4x=225m

9x=225m
