Answer:
900 cm²
Step-by-step explanation:
Perimeter of a rectangle is given by
P=2(l+w)
Where l and w are length and width respectively.
Substituting P with 120 cm
120=2(l+w)
Divide both sides by 2
60=l+w
Making w the subject of formula
w=60-l
Area, A=lw
Substitute w with 60-l
A=l(60-l)=60l-l²
Since A=60l-l²
Get the first derivative of A with respect to l
0=60-2l
l=60/2=30
Therefore, w=60-l=60-30=30
The length abd width are both 30cm. This is a square and a square is also a type of rectangle since it has four sides.
Area=30*30=900cm²
Elio bought the turkey while it was on sale for $4/pound. We need to know how much they paid, not how much they saved on the sale. The price that the turkey usually costs is not important to answer this question. So the fact that turkey usually costs $5.50 is not needed to solve the problem.
Liz is correct. Louis accidently rounded down instead of rounding up. He should've rounded up because 5 or more is rounding up.
3% is the same as 0.03
Therefore, 662/3% = 662/0.03
