Question

an isosceles triangle has perimeter 50 cm and each of equal sides is 20cm find the area of the triangle by heron's formula

Answer 1

Answer:

Step-by-step explanation:

The three sides are a=20cm, b=20cm and c = 50cm

( In isosceles Triangle 2 sides are equal)

S=20cm+20cm+50cm/2

S=45cm

Heron's Formula= √S(S-A)(S-B)(S-c)

=√45(45-20)(45-20)(45-50)cm

=√45x25x25x(-5)cm

=25x(-5)x3cm

= -125x3cm

= -375cm²
