Question

Find the areas of the following scalene triangles whose sides are given. Also
find the length of the height corresponding to its largest side. Round off to
one decimal place where necessary.
a. 5 cm, 12 cm and 13 cm​

Answer 1

Step-by-step explanation:

Area of scalene triangle =√s(s-a)(s-b)(s-c)

s=a+b+c/2

5+12+13/2=30/2

s=15

area=√15(15-5)(15-12)(15-13)

√15*10*3*2

√900=30sq.cm
