Answer 1

Let sides be 3x , 5x and 7x

Perimeter = Sum of all sides

15x = 300m

x = 20

Sides

3×20=60m

5×20=100m

7×20=140m

By herons formula

s= a+b+c ÷2

s=300/2

S=150

Formula

underroot s(s-a)(s-b)(s-c)

formula mein rkh dena aa jayega area

phir bhi kr dete h

under root 150(150-60)×(150-100)×(150-140)

root 150×90×50×10

root 3×50×3×3×10×50×10

50×3×10 root 3

=1500√3m²
