A formula helps you or tells you what to do to find the are, perimeter, volume of any shape. A = 1 x w is a formula to find an area of a 2-d figure. it is a formula becuase it tells you what to do to find the area.
There is a lot of numbers
Answer:
b is greater than or equal to 5
So square feet is area which is legnth times width or area=lw or a=lw
width=w=2 2/4
2/4=1/2
w=2 1/2=5/2
a=lw
11 11/16=187/16
187/16=l(5/2)
multiply both sides by 2/5 to clear the fraction (1/2 times 2/1=2/2=1)
374/80=legnth
simplify
374/80=187/40=4 27/40=legnth
legnh must be less than 5 and 4 and 27/40 is less than 5 so it will fit
