S1/S2 = 1/16
Thus R1/R2 = 1/4
So V1/V2 = 1/64

Answer: B
Step-by-step explanation:because my teacher said she having trouble
Answer:
A = (100 - y)y
Maximum area = 2500 sq. feet.
Step-by-step explanation:
Let the length of the combined rectangular area is y feet and the shared width is x feet.
So, perimeter of the two rectangle together is (3x + 2y) = 200 {Given}
⇒ 2y = 200 - 3x
⇒
...... (1).
a) Now, area of the total plot in sq. feet is
........ (2)
So, this is the expression for area A in terms of length of shared side x.
b) For area to be maximum the condition is 
Now, differentiating equation (2) on both sides with respect to x we get

⇒ x = 33.33 feet.
So, from equation (1) we get 
⇒ x = 50 feet.
So, the value of maximum area = 50 × 33.33 = 1666.5 sq. feet. (Answer)
