Answer:
42.4 km
Step-by-step explanation:
a parallelogram has four sides with each two sides being the same as the other two
so we can do
4.2 + 4.2 + 17 + 17
to find out the perimeter
8.4 + 34
42.4 is your answer
Answer:
Step-by-step explanation:
The perimeter is the distance all the way around the outside. It has four sides, but they only gave you two numbers. Well, the opposite sides have the same length. A parallelogram looks kind of like a rectangle that got pushed over.
The sides (all four sides) would be lengths 4.2km, 17km, 4.2km, 17km
Just add up these four sides... 4.2+17+4.2+17=42.4
The perimeter is 42.4km
