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
