Answer:
Answer is D. 54 mm^2
Step-by-step explanation:
To find area, multiply the length by the width.
For this problem, the shape is irregular so you will want to break it into two parts...a 9 by 5 rectangle and a 3 by 3 square.
First calculate the area of each shape.
9 x 5 = 45
3 x 3 = 9
Then add up the numbers.
45 + 9 = 54
Your answer: The area of this shape is 54 mm^2
Hope this helps!!
