Answer:
Step-by-step explanation:
both the length and the width of a square is the same measurement.
so if both measured to "x" then that means one side increase +7.
so one side is x + 7
and the other side decreased -4
so the other side is x - 4
area of square = length x width or just one of the sides to the power of 2
so (x+7) * (x-4) = Area
x^2 + 3x - 21 = area
The answer would be 1 1/2 think of it as 3-2 and then 5/8 - 1/8
I estimated to 45 then divided 21 and got about 2.1
