Answer:
Step-by-step explanation:
As we know that,
Area of isosceles triangle= 1/2 *b*h
we have a=10 and other side = hypotenuse=b=13 cm
Now e have formula to find h,
h=[tex]\sqrt{b^{2} -a^{2}/4}[/tex]
now putt the values ,
we get,
h=[tex]\sqrt{169-100/4}[/tex]
h=[tex]\sqrt{576/4}[/tex]
h=12 cm height of isosceles triangle ,
Area = 1/2 * b*h
Area=1/2*13*12
Area=S=60[tex]cm^{2}[/tex]
