Hope this is straightforward.
Answer:
360
Step-by-step explanation:
(i think that is a 1 not an L)
21 + 9 equals 30. And 21-9 equals 12. So you would multiply 30*12 which gives you your answer!
<h2>360</h2>
Area of a rectangle = b*h... so 6ft*5ft = 30 ft^2
%change=100(final-initial)/initial
%change=100(17.43-21)/21
%change= -17%
