In the given figure ABCD is a parallelogram. If area of parallelogram ABCD = 1728 square units, then area △ BEC = ____ square units.
If a triangle and a parallelogram are on the same base and between the same parallels, then the area of the triangle is equal to half the area of the parallelogram. So, Area △ BEC = 12 × Area parallelogram ABCD Area △ BEC = 12 × 1728 = 864 square units |
