Explanation:

Step1: Divide figure into rectangles

We can divide the given figure into two rectangles.

Step2: Calculate area of first rectangle

The first rectangle has length $45$ and width $20$. Its area $A_1 = 45\times20=900$.

Step3: Calculate area of second rectangle

The second rectangle has length $12$ and width $6$. Its area $A_2=12\times6 = 72$.

Step4: Calculate total area

The total area $A=A_1 + A_2=900+72 = 972$.

Answer:

$972$
