1. Draw the altitude opposite it will be an angle of 30 degrees because in a parallelogram the sum of the angles is 360 degrees and the opposite angles are equal. By the theorem: In a right-angled triangle the cathetus lying against the angle of 3 degrees is equal to half the hypotenuse. Then the height of the parallelogram is 10 2=5 and the area 12*5=60 cm2. The height of a rhombus is equal to the product of the height by the side; then the side=12 2 4=5 cm 3. According to the formula, the area of a triangle=half the product of the height by the base. Let x be the base then base=4x the area is 1 2x*4x=2*x^2=72 x^2=36 x=6 is the side and height then 4*6=24 cm
