Question

The base angle of an isosceles triangle is 12 . Perimeter is 32 find its area

Answer 1

Answer:

Hey mate here is the answer

Step-by-step explanation:

let the first side be X

then, the second side=X

Base=12

perimeter of triangle=sum of all sides

=32=X+X+12

=32=2x+12

=32-12=2x

=20=2x

=10=X

thus the side of the triangle=10cm

Area of triangle=1/2*Base*Height

=1/2*12*10

=6*10

=60cm^2
