ort Answer Type Questions (Slab-1) Find the area of the triangle, the lengths of whose sides are 18 cm, 24 cm and 30 cm.​

Answer 1

Answer:

We use here herons formula

area of triangle = √s(S-a)(s-b)(s-c)

s=a+b+c/2

s=18+24+30/2

s=72/2

s=36

√s(S-a)(s-b)(s-c)

√36(36-18)(36-24)(36-30)

√36(18)(12)(6)

√6*6*3*6*2*6*1*6

6*6√3*2*3*2

6*6*3*2
