Question

The perimeter of a triangle is 180 cm and its sides are in the ratio 2: 3:4. Find the area of the
triangle.
​

Answer 1

Let side of the park be, a=5x,b=6x,c=7x

also, 2s=180m,

s=90m

now, a+b+c=180

5x+6x+7x=180

x=10

∴a=50m,b=60mbc=70m

Area of park= 90(90−50)(90−60)(90−70)

= 90×40×30×20

= 3×30×2×20×30×20

=20×30√6

=600 √6 m²

Answer 2

Answer:

Let the side be x

so,2x+3x+4x

9x =180 ( area of triangle)

180÷9

20

2×20= 40

3× 20= 60

4× 20= 80
