The correct answer is 4 3/4 or 4.75
If she missed 5 points out of 100 she got 95 right...
then divide 95 by 100
95/100 to get 0.95
So 0.95 is the answer
She got 0.95 of the answers correctly
Area of paralellogram=legnth times height
l=legnth
h=height
area=96
lh=96
h is 4 less than l
h=-4+l
sub
l(-4+l)=96
-4l+l^2=96
minus 96 both sides
l^2-4l-96=0
factor
(l-12)(x+8)=0
set to zero
l-12=0
l=12
l+8=0
l=-8, imossible, legnth cannot be negative, disreagard this soultion
legnth=12cm
Its c hope I helped
