Mahalo math expert Allison Moffett shows you how to calculate square footage.

Step 1: The Square Footage of a Square or Rectangle
---------------------------------------------------------------------

1. Carefully measure one full side of the room or area with a tape measure, to the nearest inch

2. Convert feet to
inches by multiplying the number of feet times 12, and then adding any leftover inches to that figure
3. Write down the length that you measured

4. Now measure the side perpendicular to the one you just measured

5. Convert to inches

6. Write this down

7. Multiply the number of inches of both sides together

8. Divide this number by 144 to find the square footage

Step 2: The Square Footage of A Triangle
---------------------------------------------------------------------

1. Measure the distance between two corners of the triangle

2. Convert to inches by multiplying the feet times 12, and then adding on the leftover inches

3. Write down your measurement

4. From the opposite corner, measure down in a straight line so that you meet the wall that you just measured at a right angle

5. Convert to inches

6. Write down that measurement

7. Multiply both of your numbers together

8. Divide the total by two--this will give you the area in square inches

9. Divide this number by 144 to get the square footage of your triangle

Step 3: How to Get the Square Footage of a Circle
---------------------------------------------------------------------

1. Measure the entire width of your circle

2. Convert to inches by multiplying feet by 12, and then adding the leftover inches to this number

3. Divide this number by 2 to get the
radius
4. Square the radius (multiply it times itself)

5. Multiply this number by 3.14 (
pi)
6. Divide this by 144 to find the square footage

  • i watched this because of ma homework

    

  • thank you

  • @Krazemoekrazy That's right, 1 square foot 1ft. x 1ft. is a 12in. x 12in. square so 12x12 is 144sq.in

  • Thanks for the video, but i wanted to also see the conversion of inches to sq.ft.I found this browsing correct me if i'm wrong. sq.ft = Product of inches(area) \144(?)

  • Thanks for the Video, very simply taught!
