Answer:
B. 200 mm²
Step-by-step explanation:
The area of a rectangle part of the figure is found using length x width, which in this case is 25 x 2 = 50 mm²
The area of a triangle is found using [tex]\frac{base*height}{2}[/tex]. Since the values given are the legs that make up the right angle, your base and height are 15 mm and 20 mm. This means the area is [tex]\frac{15*20}{2}[/tex], which is 150 mm².
The area of the figure as is whole is 50 + 150, which is 200 mm².
