The area of a parallelogram is 24 square centimeters. What is the area of the triangle with its equal base and height?
Answer: the area of the triangle is 24 △ 2 = 12 (square centimeter)
The area of a parallelogram is 24cm2, the height is 8cm, and the base is______ Cm, and the area of the triangle equal to its base and height is______ cm2．
24 △ 8 = 3 (CM),
24 △ 2 = 12 (square centimeter),
A: the base of the parallelogram is 3cm, and the area of the triangle equal to its base and height is 12cm2
So the answer is: 3; 12
