Answer:

Step-by-step explanation:

We khow that ABCD is a parallelogram so its area is the product of the base (DC) and the the height

  • Let H be the height of the paralellogram and A its area
  • So A= DC*H

ADE is a triangle . Its area is the product of the height and the base(DE) over 2

  • We notice that the paralellogram and the triangle have both the same height
  • Let S be the area of the triangle
  • S= (DE*H)/2= DE/2 *H = DC *H

So the triangle and the parallelogram have the same area
