pls answer

Answer 1

GIVEN:- perimeter = 540m
and sides are in ratio 25:17:12
So, the sides are 25x , 17x , 12x where x is any positive no.

then ,25x + 17x + 12x = 540 

54x = 540 

x = 10 

25x = 25 * 10 = 250
17x = 17*10 = 170
12x = 12*10 = 120

So, the sides are 250m , 170m & 120m. 

now, the semi - perimeter is S = 540/2 = 270 m

we know the Heron's formula:-

area of triangle =
where, a,b,c is the sides of triangle and s is the semi-perimeter. 

now, the area of the triangle is 
= m²

= m²

= m²

= m²

= 9000m²


Hence, the area of triangle = 9000m²
