Answer:
Step-by-step explanation:
let the side of outer square=2x
then x²+x²=(20√2)²
2x²=800
x²=400
x=√400=20 in
2x=2×20=40 in
area of outer square=40²=1600 in²
area of inner square=(20√2)²=800 in²
area of shaded region A=1600-800=800 in²
Fractions: 4/8, 1/2
Percent: 50%
Decimal: 0.50
A polynomial with a degree of 2 can be:
x² + 1
y² + 2
etc..
