Answer:

=2√2 the fourth choice.

Step-by-step explanation:

We can use the Pythagoras theorem to calculate the value of y.

a²+b²=c²

a=1

b=y

c=3

Therefore substituting for the values in the theorem above we get:

1²+y²=3²

Leave y on one side.

y²=3²-1²

y²=9-1

y²=8

y=±2√2 in surd form.

Since we expressing length, a scalar quantity, we take the modulus of our answer. Thus y=2√2

The area of a square of side s is
.. A = s^2

The area of a circle of diameter s is
.. A = (π/4)s^2

The area of the yellow region is the difference between these when s=5 ft, so is
.. (5 ft)^2*(1 -π/4) ≈ 5.4 ft^2
