What is the perimeter of this figure

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
