Question

3. Find the area of the triangle whose sides are 18 cm, 24 cm and 30 cm.
Also, find the height corresponding to the smallest side.
The sides of triangle are in the ratio 5.12.13 and its perimeter is
1

Answer 1

s = a+b+c÷2

18+24+30÷2=36cm

AREA OF TRIANGLE =

Step-by-step explanation:

$\sqrt[2]{s(s - a)(s -b )(s - c)}$

=

$\sqrt{36(36 - 18)(36 - 24)(36 - 30)}$

=

$\sqrt{46656}$

area=216cm²

°.°area = ½*b*h

216=½(18)(h)

216*2/18=h

h=24cm
