question #3.

**the relationship between the area of a rectangle and the area of a triangle:**

the relationship beteww the two is that a rectangle is made up of two triangle, that are right triangles ( a right triangle is a triangle with a 90 degree angle)

**Mr. Tamayo's Comments:**

"good job on the math"

__DAY #2__

here's what i did:

now, to find the total surface area (T.S.A) you add the two areas together

so it would be like this:

T.S.A= A+B

T.S.A= 50+56

T.S.A= 106cm2

now to solve it a 2nd time, but different:

how i solved this a sceond time is that i calculated the measurments all the way around the shape. i added the the missing piece in the shape making it a complete rectangle. then when you find the total surface area, you subtract the missing shape from your answer. so it would be like this:

A= AB-M (ab for rectangle a & b, and m for the missing shape)

A= 120-24

A=96cm2

so thats how i did this question... hope i did it right! ill be back for the next question =D

**Mr. Tamayo's comments:**

*" your good, i forgot how to do this"*

__DAY #3__

now to show what i did to solve this question

so i guess i have to go and leave comments now! =) so, ill be back with day 4 =D

**Mr. Tamayo's comments:**

*"another comment.... hmmm... good!"*

__DAY #4__

__(The Weekend and March 20)__

heres my rectangular prism:

next i did this:

to find the anxwer, you simply add them all together, like so:

35 + 35 + 28 + 28 + 20 + 20= 166 cm2

i will get my dads comment tomorrow... cuz hes sleeping

**Mr. Tamayo's comment**

*"ugh.. what... umm.... good"*

__DAY #5__

(yeah! finially blogger worked..... tried MANY MANY times)

time for another picture! (used someother uploaded because the one on blogger wasnt working, will fix it later!)

**click mee!!**

next i drew out all the sides(/ or shapes?)

**click mee!!**

to figure out the total surface area you add all the total areas together, like so....

20 + 20 + 40 + 50 + 60= 190 cm2

so thats how i did it!

**Mr. Tamayo's comment**

*"good.... im trying to sleep"*
