Question

the perimeter of triangular field is 450 M and its sides are in the ratio 13 :12 : 5. find the Area of triangle

Answer 1

perimeter = 450m

let supoose one side = 13x
and 12x and 5x

now 13x+5x+12x =450

30x = 450

x = 450/30

x = 15

now sides are

13 × 15 = 195


12×15= 180

5×15= 75

now s = 450/2

s = 225

now root under s(s-a)(s-b)(s-c)

now put the value u will get the answer

Answer 2

HEY BUDDY..!!

HERE IS UR ANSWER...

________________________.

=> Perimeter of field is give 450 m

=> Perimeter is sum of all sides________( 1 )

Ratio of sides are 13 : 12 : 15

Let side be x ...

According to statement 1

=> 13x + 12x + 5x = 450

=> 30x = 450

=> x = 15m

So ,

=> Sides are

⏺️13 × 15 = 195 m
⏺️12 × 15 = 180 m
⏺️5 × 15 = 75 m

HOPE HELPED..

HAVE A NICE DAY..
