Question

1. Find the area of a triangle whose sides are 18
cm, 24 cm and 30 cm.
Also, find the length of altitude corresponding
to the largest side of the triangle.​

Answer 1

semi perimeter = 72/2=36

area=√s(s-a)(s-b)(s-c)

=√36(36-30)(36-18)(36-24)

=√36×6×18×12

=√2×3×2×3×2×3×3×3×2×3×2×2

=2×2×2×3×3×3

=216cm^2

area =1/2×h×b

216=1/2×30×h

432=30×h

14.4cm=h
