OK, well it is A=bc2 A = Area b = One Diagonal c = Other diagonal The area is unknwon, but what are the two diagonals given? .

|dw:1438210389431:dw|

OpenStudy (jdoe0001):

hmmm actaully... don't even need that just get the area of the triangle|dw:1438210669972:dw|

OpenStudy (jdoe0001):

and notice, you have 4 triangles

OpenStudy (anonymous):

Ok and can you give me a hint for the answer please?

OpenStudy (anonymous):

That is what I was thinking. Get the area of the tri and then times by 4

OpenStudy (jdoe0001):

yes, hint: check your book on the "area of a triangle"

OpenStudy (anonymous):

What book im doing virtual school

OpenStudy (jdoe0001):

well... study material just because is online classes, I'm pretty sure you're not exempted from studying material

OpenStudy (anonymous):

Area of tri = \(\huge \frac{1}{2}bh \)

OpenStudy (anonymous):

\( \huge b = \frac{12.6}{2}\) \( \huge h = \frac{10.4}{2}\)

OpenStudy (anonymous):

So i divide them the multiply them for the answer/ @Nixy

OpenStudy (anonymous):

*then

OpenStudy (anonymous):

You multiply \( \huge \frac{1}{2} \times \frac{12.6}{2} \times \frac{10.4}{2} = ?\) and then times that value by 4

OpenStudy (anonymous):

i still dont get it but thanks for the help

OpenStudy (anonymous):

Do you know how to times that ?

OpenStudy (anonymous):

Nope

OpenStudy (anonymous):

What is 1 times 12.6 times 10.4 ???
