Question

Find the area of the isosceles triangle.

Answer 1

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=$\sqrt{b^{2} -a^{2}/4}$

now putt the values ,

we get,

h=$\sqrt{169-100/4}$

h=$\sqrt{576/4}$

h=12 cm  height of isosceles triangle ,

Area = 1/2 * b*h

Area=1/2*13*12

Area=S=60$cm^{2}$
