Calculate the Area of a Deltoid: 8x11 Unit Dimensions Problem

To solve this problem, we'll follow these steps:

• Step 1: Identify the given information.
• Step 2: Use the appropriate formula for area calculation.
• Step 3: Perform the calculation using the formula.

Now, let's work through each step:
Step 1: We recognize that the vertical diagonal $AC = 8$ cm and the horizontal diagonal $BD = 11$ cm.
Step 2: We'll use the formula for the area of a deltoid (kite), given by
$A = \frac{1}{2} \times d_1 \times d_2$, where $d_1$ and $d_2$ are the lengths of the diagonals.
Step 3: Plugging in our values, we get:
$A = \frac{1}{2} \times 8 \times 11$
$A = \frac{1}{2} \times 88$
$A = 44$ cm².

Thus, the area of the deltoid is $44$ cm².
