Answer 2

Answer:

9000 cm2

Step-by-step explanation:

SOLUTION

Ratio of the sides of the triangle = 12:17 :

25Let the common ratio be x then sides are 12x, 17x and 25xPerimeter of the triangle

= 540cm12x + 17x + 25x = 540 cm = 54x =

540cm = x = 10 Sides of triangle are,12x = 12

x 10 = 120cm17x = 17 x 10 = 170cm25x = 25 540/2 = 270cmUsing heron's formula, Area of

× 10 = 250 mm Semi perimeter of triangle(s) = =

the triangle = vs (s-a) (s-b) (s-c)

- 250)cm2

= = v270(270 - 120) (270 - 170) (270

= v270 x

150 x 100 x 20 cm2

9000 cm2
