Question

find the area of the triangle whose sides are 10 cm 6 cm and 4 cm​

Answer 1

Answer:

Not possible to have triangle with sides 10 cm 6 cm and 4 cm​

Step-by-step explanation:

Not possible to have triangle with sides 10 cm 6 cm and 4 cm​

In any triangle, the sum of the lengths of any two sides must be greater than the length of the third side. Or, to put it a different way, take the shortest two lengths and add these together. This sum must be greater than the length of the longest side.  

If the sides measure 4 cm, 6 cm and 10 cm, the triangle does not close! You see, 4 cm + 6 cm is not greater than the length of the longest side, 10 cm. The longest side must be somewhat shorter than 10 cm (but still longer than 2 cm).

please ignore the part below.

Area of triangle = sqrt[ s(s - a)(s - b)(s - c) ]

s= Semi perimeter = (a+b+c)/2=20

Area of triangle=  sqrt[ 20(10)(14)(16)]

Area of triangle=  sqrt[ (10*2)(10)(2*7)(16)]

Area of triangle=  80sqrt[7]
