ABCD is a parallelogram and AE perpendicular to DC if AB is 20cm. and the area of parallelogram is 80cm. then find the AE which is 90degree?

as with any parallelogram, the area

A = bh

base * height

4 cm

4cm

To find the length of AE in the given parallelogram, we can use the formula for the area of a parallelogram.

The area of a parallelogram is given by the formula:
Area = base × height

In this case, we know the area of the parallelogram is 80 cm², and we are given the length of AB, which is the base of the parallelogram (20 cm).

Using the formula, we can say:
80 cm² = 20 cm × height.

Now, we can solve for the height by dividing both sides of the equation by the length of the base (20 cm):
80 cm² / 20 cm = height.

Simplifying the equation, we get:
4 cm = height.

So, the height of the parallelogram, which is the length of AE, is 4 cm.
