Part A: Describe how you can decompose this shape into triangles. (2 points) Part B: What would be the area of each triangle? (5 points) Part C: Using your answers above, determine the area of the table's surface. (3 points)
and i bet this is a regular polygon that means all side lengths are equal
can you decompose this thingy into triangles
Yes you can decompose it into 6 triangles
so like this by the way my polygon is horribly drawn |dw:1438911736430:dw| anyways each of these triangles is suppose to be the same shape as each other
it looks good
is we divide 12 by 2 what do we get
i mean if not is but yes right
actually we didn't need that :p
|dw:1438911894424:dw| what is the base of this triangle?
base length that is
well that is the height of triangle I tried to darken
what is the base length
do you know how to find the area of a triangle given its height is 10.4 and its base is in 12 and just pretend i put the units is inches for each of those :p
yes a=1/2* b*h
right so .5*12*10.4 =?
i thought it was 1/2 * 10.4 *12?
it is I just didn't feel like writing a fraction 1/2 is the same as .5
they are the same number
oh so the answer is 62.4
yes earlier you told me you had 6 of those triangles though
so you could do 62.4+62.4+62.4+62.4+62.4+62.4 or just do 6(62.4)
that is right
and just to be more concise we are going to be in^2 at the end
area has units squared
so the area of the area of each triangle is 62.4?
not bad right?
honestly it seemed harder but you made it easier
i'm glad i could make things easier for ya
Bye (: Thanks
I appreciate your help c:
