( IF THE GUY WHO ANSWERS MY IS FROM SOUTH POINT SCHOOL THEN WRITE "SPHS" AFTER WRITING THE ANSWER)

Answer 1

Answer:

48cm^2

Step-by-step explanation:

As the other two opposite sides are of equal length. Therefore length of the other two sides= (32-12) = 20 CM of both the sides

length of one of the opposite sides = 20/2 = 10cm

Now as area of a triangle is 1/2 x base x height

base - 12cm

height-?

Draw a line perpendicular to the base

Now by pythagoras method,

h^2 + 6^2 = 10^2

h^2 + 36 = 100

h^2 = 100-36

h^2 = 64

h = √64

h = 8 cm

Now find the area,

1/2 x 12 x 8 = 48cm^2
