Question

medians of a triangle are 9cm 12cm 15cm.what's the area of the triangle

Answer 1

Hii friend,

Let, M1 = 9cm , M2 = 12 , M3 = 15cm

Sm = 1/2×(M1+M2+M3)

Sm = 1/2×(9+12+15)

Sm = 1/2×36 = 18 .

THEREFORE,

S-M1 = 18-9 = 9 CM

S-M2 = 18-12 = 6 CM

S-M3 = 18-15 = 3 CM

THEREFORE,

AREA OF TRIANGLE = 4/3 × ✓S(S-M1)(S-M2)(S-M3)

PUT VALUES AND SOLVE...U WILL GET THE AREA OF TRIANGLE...


HOPE U GOT IT.... :-)
