Answer:
20
Step-by-step explanation:
A: 0.171 m, because 1 meter is 1,000 mm, and there is only 171 mm total.
My guess is length of side B would be 12. This is my estimation, I remember a bit on how to do these but since it’s a triangle, I’m thinking the sides are going to be 1/2 of the base. In this case, the base is 24, so the sides should be 12.
