Question

examine whether the triangle having sides 60m,40m and 30 m is well condition or not?​

Answer 1

Answer:

yes it is well condition

Step-by-step explanation:

as the sum of any two sides is always greater than the 3rd side

Answer 2

Step-by-step explanation:

Area of parallelogram=2times area of triangle with sides 60,40,80

Let a= 60b=40c=80

s= (a+b+c)/

= 90

s-a = 10

s-b = 50

s-c = 10

Area of triangle √s(s-a) (s-b) (s-c)

√90×30×50×10

100√3×3×3×5

300√15

so area of parallelogram

600√15 is answer
