Question

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

Answer 1

Answer:

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
