• hi my question is what is a foot?
• A foot is equal to 12 inches. A foot is also equal to 30.48cm.
• Could it still work on a different shape?
• so you are counting the squares you see in the quadrolatrul thing
• What about if you have 3 half's
• What about the area covered by the lines drawn is that left out of the calculation or counting?
• this is so hard i don't get it help me
• it looks like stairs
• What is Measuring area with partial unit squares, im confused
• How is area suppose to to be the same as perimeter?Or is it not?

• Area and perimeter are actually different. Think of area as a garden - it is the dirt inside of the garden. Area describes how much space is inside of a figure.
Perimeter, however, is different. Perimeter describes the outside of a figure. Think of it as a fence around a garden. It basically describes how big of a 'fence' a shape would need.
Hope this helped!

• How can we count the partial area of a square?

• Here's an example:
Okay, so, a partial is 1/2 (half)
So, if there were 2 halves you would add them together, thus making 2/2 which is a whole. For each half there is you need to combine them to make a whole.
6 partials would become 3 wholes.
4 partials would become 2 wholes.
2 partials would become 1 whole, etc.
After you add all the partials together take the number you got from that and add it to the whole units within the square and that's your answer.
