Answer:

538.3

Step-by-step explanation:

First of all find the area of the rectangle

L*W

15*30

450

Now find the area of semi circle

1/2[tex]\pi r^{2}[/tex]

Since radius is half a diameter divided 15 by 2=7.5

1/2[tex]\pi 7.5^{2}[/tex]                            7.5 times 7.5= 56.25

1/2*3.14*56.25

56 times 3.14 is 176.625 now multiply 176.625 by 1/2

Answer is 88.3125

Now add 450 to 88.3125

Final answer: 538.3125
