How to Measure a Triangle's Area

So you want to know how to measure a triangles area huh?Well it's easy!First you take a triangle(any size or length).Then try to draw one that's the exact same size and length.Flip ONE of the triangles and and attach it to the other triangle and make either a rectangle or parallelogram.Then you measure the parallelogram or rectangle(on another post) and divide that awnser by two and you have your awnser!

How To Measure the Area of a Paralellegram

To find the area of a paralellegram,there are two ways,one you measure the L and the W. Then times the L by two and the W by two.Then times the numbers that you got from the L and W and you have your awnser(be sure tomake it cm,m or km squared).The second way is you can cut (not literally)from the top part of the parellelgram.Then drag it over to the side where it's slanted and make a rectangle.Then you measure the W times the L and you have your awnser.

Question on March.13/2007

Milimeters: Well the questions says "The perimeter of a triangle is 16cm(160mm) .What is the missing measurement?(picture in my math book)Record your work on your journal blog,the measurement in cm and mm. (This is not an equalateral triangle).One side is 41 mm(4.1cm).Another side is 5cm(50mm).So all I did was add 41mm+50mm(which is 91mm)(9.1cm)and then subtracted 160mm(16 cm)from 91mm(which is 69mm).So then I found out that the missing measurement was 69mm.

Centimeters:Well I did the same thning a s the milimeters but in centimeters so one side was 4.1cm(41mm),another was,5cm and I added those two together to get 9.1 and subtracted that from 16cm (which is 6.9cm). So add 6.9cm with 4.1cm and 5cm and you get 16 centimers.

math pg (277)(my journal)

I think it's quite easy becuase I've already done this type of unit.To me it's just like a review(a little bit).But SOME of the questions mix me up.

Patterning unit response

For this unit of patterning I found lots of it easy, like the input(X) and output(Y). I felt like I could finish the work we where assigned in about 2 minutes! I thought the mini quizzes were quite easy. I think patterning was one of my best units! I'm not really a math fan but I actually liked doing thjis unit because I'm good at patterning. The thing I found the easiest was X and Y.
