Anything multiplied by 0 =0
So what is left is 90x100x12x13x34 which is=47,736,000
A: 100m^2
10 x 10 = 100
B: 28.274m^2
You have to do pi x r squared
So,,,
Pi x 3^2
9pi = 28.274....
C: just subtract the grass bed from the land...
100 - 28.274 = 71.72566612...
So C is 71.726m^2
Hope this helped! Have a nice day :)
