Question

Pls help now im desperate

Answer 1

yes he is right it is 9 from the math

Answer 2

42 ft^2

Subtracting ‘blank’ space from a larger figure:
(5*12) - (6*3) = 42
60 - 18 = 42
5*12 = 60
6*3 = 18

Breaking down the figure into smaller figures:
(12*2) + (3*3) + (3*3) = 42
12*2 = 24
3*3 = 9
3*3 = 9
