Step-by-step explanation:

please make me brain list

Answer 2

Answer:

hi

first p=2a+b where a is length of two equal sides and b is base so p=2×(10+6)

=32cm

and area of isosceles triangle =1/2b×h

and to find hight use Pythagorean theorem and get the answer

therefore h= 36cm^² and find it's root =6 and h=6

so, A=1/2(6×6)

=1/2(36)

=36/2

=18cm^²
