Answer:
100mm
Step-by-step explanation:
Perimeter is the size of the outer part of the figure. And in this figure, we have a triangle and a semicircle joined together.
Formulae for finding the perimeter of a circle is 2πr, and since it's a semicircle, we divide the answer by 2. Where π is 3.14
2(3.14)(16)/2
50.24
Adding the other parts
50.24+40
90.24
Rounding up to the nearest hundred, we have the number between 0 and 100. 90 is closer to 100 than 0.
Hence, the answer is 100
