To find the area of the remaining part of the rectangle, we need to calculate the area of the rectangle and then subtract the area of the removed triangle.
First, let's find the area of the rectangle. The formula for the area of a rectangle is length times width. Given that the length of the rectangle is 18 mm and the width is 15 mm, the area of the rectangle is:
Area of rectangle = 18 mm * 15 mm = 270 mm²
Next, let's find the area of the removed triangle. The formula for the area of a triangle is 1/2 times base times height. Given that the height of the triangle is 9 mm and the base is the sum of the lengths to the left and right of the triangle (3 mm + 9 mm = 12 mm), the area of the removed triangle is:
Area of triangle = 1/2 * 12 mm * 9 mm = 54 mm²
Finally, we can find the area of the remaining part of the rectangle by subtracting the area of the triangle from the area of the rectangle:
Area of remaining part of rectangle = Area of rectangle - Area of triangle
= 270 mm² - 54 mm²
= 216 mm²
Therefore, the area of the remaining part of the rectangle is 216 mm². The correct answer is B.
