Question

find area of a triangle two sides of which are 16 cm and 22 cm and the perimeter is 64 CM​

Answer 1

Answer:

semi perimeter =perimeter/2

=64cm/2

32cm

third side = 64cm -(16cm+22cm)

=64cm-38cm

=26cm

using heron formula

area of triangle √(s*(s-a)(s-b)(s-c)

=√(32*16*10*6)

=32√30

=32*5.47

=175.2cm²
