Answer:
The length of the other side is 7.65m
Step-by-step explanation:
Maria's mistake was that she wanted to move the decimal point 2 places to the left, when she should have moved it 1 place, since that is the number of zeros that the number 10 has.
To find the length of the rectangle, we simply divide the area by the width
a = area = 76.5 m
w = width = 10m
l = length
l = a/w
l = 76.5m² / 10m
l = 7.65m
The length of the other side is 7.65m
Axis of symmetry:
-b/2a= -(-1)/2(2)= 1/4
Y-intercept:
(0,3)
