Answer: she made 11 sparkelers and gavin made 21
Step-by-step explanation:
Area = length x width
replace the known information into the equation:
area = 2/3
width = 1/2
so now the formula looks like:
2/3 = 1/2 x L
to solve for L we divide both sides by 1/2
L = 2/3 / 1/2 which = 2/3 * 2/1 = 4/3 = 1 and 1/3 km
If they have -8 points and +6 points, that'd leave them with a total of -2 points.
So the answer is -2.
