Question

find the area of issocles x= side are 13cm and bases 24 cm​

Answer 1

Step-by-step explanation:

let the sides of the isocles triangle be a,b and c

where c is the base and a and b are the sides of the triangle

c(base)=24cm

a=b=13cm(opposite sides of the isocles triangle are equal

,semi-perimeter=a+b+c\2

=13+13+24/2

=25cm

By using heron's formula

✓s(s-a)(s-b)(s-c)

=✓25(25-13)(25-13)(25-24)

=✓25X12X12

=✓5X5X3X2X2X3X2X2

=5X3X2X2

=60cm^2

hence,the area of the isocles triangle is 60cm^2
