A is the correct answer i'm pretty sure
If i used the correct numbers for the base and the height the area of the triangle would be 182
Hi,
L = (1/6)x - 1
P = 2x + 2L = 2x + (2/6)x - 2
P= (7/3)x - 2
x being the width.
Hope this helps!
6 / 9 = 2/3 ( since dividing top and bottom be 3 gives 2/3)
Also 4/6 = 2/3
No her estimate is to low because if you multiply 15.5 by 12 you get 186
