Answer:
3 in²
Step-by-step explanation:
The fraction 9/16 is equal to the equation 9 ÷ 16.
9 ÷ 16 = 0.5652
Lets find the square root of 0.5652

So the length of one side is 0.75 in²
Now we'll multiply this by 4, for the length of the 4 equal sides.
0.75 x 4 = 3.
This means the perimeter is 3 in².
4b²+20b+25=0
Divide everything by 4
b²+5b+ 6.25=0
use the quadratic formula
x= (-b+ or - √b²-4ac) /2a
x= (-5 + or - √5²-4*1*6.25) /2(1)
x= -5/2 so
in this case, b= -5/2
