The landis in the shape of a parallelogram ABCD. In the restof the portion medicinal plants are grown. Area of theparallelogram is 200 m2Calculate the area where medicinal plants are grown(b) Which value is depicted here?

Answer»

Area of a parallelogram = Base x altitude = 200 m²

since PD is an altitude drawn to the base DC

Hence area of the parallelogram = DC x PD = 200

Also the pond is a triangle shaped with DC as base and PD as altitude

Hence area of the pond

= 1/2 x Base x altitude

= 1/2 x DC x PD

= 1/2 x 200

= 100

Area of the medicinal plant = Area of the land - area of the pond

= 200 - 100

= 100 m²

Hence the area where the medicinal plants were grown is 100 m²
