Question

12 cm 10 cm 18 cm find the area
​

Answer 1

Answer:

21 √11sq cm

Step-by-step explanation:

Given sides are 18cm,10cm and 14cm

Area of triangle =

s(s−a)(s−b)(s−c)

⇒a=18cm,b=10cm and c=14cm

⇒s=

2

a+b+c

=

2

18+10+14

=

2

42

=21cm

Area =

21(21−18)(21−10)(21−14)

=

21×3×11×7

=21 √11sqcm

Hence, the answer is 21

√11sqcm.
