Answer B
a) Δ=8²+4*2=72
b)36-4*3*2=12
c)4²+4*1=20
d)4-4*4*1=-12
1. A square is a figure with four sides that have the same lenght. So, to solve this problem and calculate the area of the square, you must apply the following formula:
A=(s)(s)
A=s²
"A" is the area of the square.
"s" is the lenght of the side of the square.
2. So, the lenght of the side given in the problem is 5^2/5 inches (s=5^2/5 inches). Therefore, you only have to substitute this value into the formula A=s².
3. Then, you obtain:
A=s²
A=(5^2/5 inches)²
A=5^4/5 inches²
What is the area of the square?
The answer is: A. 5^4/5 square inches.
