Answer:

let the sides be 3x, 5x, 7x

ATQ, 3x+5x+7x=300

15x=300

x=300/15

x=20

area =3x*5x*7x

=105x

=105*20

=2000

Answer:

1500 root 3

Step-by-step explanation:

perimetre=300

side+side+side=300

3x+5x+7x=300

15x=300

x=300/15=20

3x=3×20=60

5x=5×20=100

7x=7×20=140

the triangle has 3 unequal sides

so it is a scalene triangle

area=root over of s (s-a)(s-b)(s-c)

s = a+b+c/2

so

root over of 150×(150-60)(150-100)(150-140)

root over of 150×90×50×10

=1500 root 3

if u think it is right
