Question

the parameter of a triangle is 450 M and its sides are in the ratio of 12 13 25 find the area of the triangle​

Answer 1

mark it as a brainiest answer

Answer 2

Answer:

Let sides are;-

12x,13x,5x.

First checking whether the triangle is right - angled triangle or not.

(12x)²+ (5x)² should equal to (13x)².

144x² + 25x² should equal to 169x².

169²=169²

Hence it is a right angled triangle.

_______,___,

Now,

Given that perimeter = 450m.

12x+ 13x+ 5x = 450

30x = 450

X= 450/30

X= 15

sides are

5×5 = 25m

12×5 = 60m

13×5 = 65m

_________.

area of right angled of triangle.

=( base×height)/2.

= Area= (25×60)/2.

Area= 25×30.

Area = 750m².

I Hope this will help you.
