Question

the base of an isosceles triangle is 12 cm and its perimeter is 32cm. find its area by pythagorous theorm​

Answer 1

Answer:

48 cm is the area

Step-by-step explanation:

perimeter of isosceles triangle is = 2a+b= 32

b= 12

2a= 20

a=20

Area = {b/4}√(4a^2-b^2)

= 12/4×√4*100-144

12/4÷√256

3*16

48cm

Answer 2

Answer:

since isosceles triangle have 2 sides equal then take both side x

perimeter =x+x+12

32-12=2x

x=20/2

x=10

s=10+10+12/2

s=32/2

=16

area=^16(16-10)(16-10)(16-12)

=^ 16×6×6×4

= ^2304

=48
