Question

A parallelogram has sides of length 4.2 kilometers and 17 kilometers. What is the perimeter?

Answer 1

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

Answer 2

42.4 km

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
