Answer:
289 in^2
Step-by-step explanation:
1. Find side of the small square: (DG=a)
64= a^2
a= 8
2. Find hypotenuse of triangle being formed: (OG=c and DO=b)
+ =
c= 17
3. Find area of square:
= A
(17)*(17)= 289 in^2
18 inches = 1.5 feet
8 inches = 2/3 foot
y = 1.5 + (2/3)x
C) y=6x^2 is widest among these.
