Area of Rectangle = length times width
lets say length = 2x-4
width = x+5
Note: you can switch these around, width could be 2x-4 and length could be x+5, it doesnt matter.
With that being said:
length * width = area
(2x-4)(x+5)=area
FOIL (First Outer Inner Last)
Simplify:
B- 1.23 You can do that whit an app name photomath :D
5 1/2 * 2 1/3 =
11/2 * 7/3 =
77/6 =
12 5/6 <===
The square root of 11 = 3.3166
which is between 3 and 4 so the first one is the answer
