Step-by-step explanation:

if we draw perpendicular on the base we get the base into equal parts so that we got two right angles in which we find the height by Pythagoras theorem and is 3 centimetre so by applying area of triangle formula we get that area of One triangle that is right angle triangle is equal to 6 because in the figure there is two right angle triangle therefore be add the area of two triangles then the resultant area will be 12 centimetre square
