378 ft I think this is the answer
Subtract the cost of the hard drive from the original $1284 and divide the answer you got by the 9 sticks of memory for your answer.
Answer:
See below
Step-by-step explanation:
It is NOT a RIGHT triangle so you <u>cannot use</u> 1/2 b * h
but you can use Heron's Formula
Area = sqrt( s (s-a)(s-b)(s-c) )
s = semi- perimeter = (3+6+7)/2 = 8
Area = sqrt ( 8 ( 8-3)(8-6)(8-7) ) = sqrt ( 80) = 8.9 cm^2
Im 99.99999% it is the top left
Try by dividing this shape into three different squares then find the area of each shape then add them together.
