Answer 2

Calculating the Area of Rectangle ABCD

To find the area of rectangle ABCD, we can use different methods. Here are a few ways to calculate the area:

Method 1: Using the Length and Width The area of a rectangle can be calculated by multiplying its length (AB) by its width (BC). So, the formula for the area (A) is:

A = AB * BC

Method 2: Using the Perimeter The area of a rectangle can also be calculated using the perimeter (P) and the length of one side (AB). The formula for the area in this case is:

A = P * AB / 4

Method 3: Using the Diagonals If the lengths of the diagonals of the rectangle are known, we can use them to calculate the area. Let's say the length of one diagonal is AC and the length of the other diagonal is BD. The formula for the area in this case is:

A = (AC * BD) / 2

It's important to note that the area of a rectangle is always positive, so we don't need to consider negative values.
