If you know the length of the side of the square, how can you figure out the area?

By multiplying

If the sides were 5 then you would do 5x5 to get the area  

Hope this makes sense :)

d. it is a convex pentagon because it has five sides and none of the sides would extend into the inside of the polygon.

step-by-step explanation:

hey! so 1 (25) out of 4 (100) is 25 so your answer is 25%. it's like quarters!
