Solution

To find the area of region BCED, we can use the formula for the area of a triangle.

First, let's draw triangle ABC with sides of length 4.

Next, we draw a perpendicular line from point D to side AB, and label the point of intersection as E.

Since AD is given as 1 cm, we can label that on the diagram.

Now, we have a right triangle ADE with a base of 1 cm and a height of 4 cm.

To find the area of this triangle, we can use the formula:

Area = (base * height) / 2

Plugging in the values, we get:

Area = (1 cm * 4 cm) / 2

Area = 4 cm² / 2

Area = 2 cm²

Therefore, the area of region BCED is 2 cm².
