OpenStudy (mrnood):

you need to post the figure However - this has been posted before Just break the figure along the horizontal centreline - you have 2 identiocal triangles (height * base)/2 is the area of each

OpenStudy (mrnood):

figure is as before - see above

@MrNood is the answer A. 98?

OpenStudy (mrnood):

I am not going to respong to guesses - 4 of them you are sure ot be right What is the base of each triangle if you do what I said? What is the height of each triangle if you do what I said? What is (height + base)/2 of each triangle What is the the sum of the 2 triangles..

Hmmm.. Okay so it is definitely NOT C. or D... Which just leaves me with A. or B...

OpenStudy (mrnood):

If you are so sure what it is NOT - why are you not sure what it IS?

OpenStudy (anonymous):

I still think it is A..
