Question

The perimeter of a triangular field is 420m and its sides are in the ratio 1:2:3. Find the area of the triangular field.

Answer 1

here this is the answer which i got after sloving .

Answer 2

Answer:

It doesn't form a triangle so no area or area = 0

Step-by-step explanation:

Given: Perimeter of a triangular field is 420 m and its sides are in the ratio 1:2:3

To find : The area of the triangular field.

Solution :

Let sides of a triangular field be a = x, b = 2x and c = 3x.

Perimeter of a triangular field, $P=a+b+c$

$420=x+2x+3x$

$420=6x$

$x=70$

Therefore, sides are a=x=70 , b=2x=140 , c=3x=210

First we check that it form triangle or not

The sum of two smaller sides of triangle is greater than third side then triangle form.

i.e, a+b > c

a+b = 70+140 = 210= c = 210

Therefore, it cannot form a triangle.
