xeze [42]
ANSWER: $65.63

Answer:

( 36 ) inches^2

Step-by-step explanation:

To find the area of non-geometric shapes we have to divide it into different segment ( image attached below)

Step 1: Area A

= 5 x 2

= 10 inches ^2

Step 2: Area B

= 4 x 4

= 16 inches ^2

Step 3: Area C

= 5 x 2

= 10 inches ^2

Step 4:  Total area ( add all)

= ( 10 + 16 + 10 ) inches ^2

= ( 36 ) inches ^ 2
