Answer:
The area of the rectangle is 27
Step-by-step explanation:
so we need our formula to find the area of a rectangle. Area = Width × Length
Now we plug our numbers in.
A = 9 × Length
Since we are missing our exact Length amount we need to figure that out first. The statement says the length is 1/3 the size of the Width and the Width is 9.
9 × 1/3 = 9/3
9/3 can be simplified to 3 thus our Length is 3. now we add this into our equation
A = 9 × 3
A = 27
I’m pretty sure it’s the first one! Goodluck :)

Answer:
42
Step-by-step explanation:
L=2W+5
LW=42
(2W+5)W=42
2W^2+5W-42=0
(2W-7)(W+6)=0
2W-7=0
2W=7
W=3.5 ANS.
L=2*3.5+5=7+5=12 ANS.
PROOF:
3.5*12=42
42=42
