Answer» Answer: 24cm Step-by-step explanation: ACCORDING to the Heron's formula, Area (A) of the triangle having sides a,b,C UNITS is A= s(s−a)(s−b)(s−c)
where s= 2 a+b+c
For the given triangle, a=18 cm b=24 cm c=30 cm s= 2 18+24+30
=36 A= 36(36−18)(36−24)(36−30)
A= 36×18×12×6
A= square root under 216 × 216 = 216 cm square Smallest side =18 cm Area of the triangle = 1/2 ×base×ALTITUDE=216 1/2 × 18 × altitude = 216 Altitude = 216/9 = 24cm. Ans. |
