Question

5. Find the area of an isosceles triangle with
perimeter 36 cm and base 16 cm.​

Answer 1

Answer:

48 is answer

Step-by-step explanation:

equal sides= 10,10

area = 1/2×b ×h

b=16

h=√10^2-8^2

=√100-64=√36=6

1/2×16×6=48

Answer 2

Answer:

let sides be x,x,b

in isosceles triangle two sides are equal

b=16(given)

perimeter=36

x+x+16=36

2x=36-16=20

x=10

height^2=10^2-8^2

h^2=36

h=√36=6

area of the triangle

=1/2*b*h

=1/2*16*6

=8*6

=48cm^2

is the area ........,
