Answer:

39.53 ft^2

Step-by-step explanation:

We can find the area of the rectangle

A = l*w

= 12*3 = 36

And the area of the semicircle

A = 1/2 pir^2

The diameter is 3, the radius is 3/2

=1/2 pi* (3/2)^2

= 1/2 *3.14 * 9/4

3.5325

Add the two areas together

36+3.532539.5325

Rounding to the nearest hundredth

39.53 ft^2

Choose the numbers that are irrational.

ddd [48]

As the numbers are written, none of them are irrational because they are all terminating decimals:

$3.624=\dfrac{3624}{1000}=\dfrac{453}{125}$
$0.6=\dfrac6{10}=\dfrac35$
$0.87=\dfrac{87}{100}$
$-5=-\dfrac51$

Perhaps there is some missing notation in your question?
