area of a parallelogram is base x height base is 6+5=11 height = 12 11*12 = 132cm square
or there are 2 triangles and 1 rectangle the triangles measure the same thing the formula for the area of a triangle is 1/2bh 1/2*6*12 = 36 area of rectangle is length x breadth 5*12 = 60 area of whole parallelogram = 60+36+36= 132cm square
