Answer:
The area of the second rectangle is
Step-by-step explanation:
Please see the picture below.
Let´s name the length of the second rectangle as x, so the length of the first rectangle will be 4+x.
The formula of the area of the rectangle is given by
Replacing values:
Solving for x:
Find the area of the second rectangle:
Step-by-step explanation:
f'(x) = 6x-12
in vertex : f'(x) = 0
6x-12 =0 => x=2
f(2) = 3 ( 2² ) -12 (2 ) +1 = -11
vertex ( 2 , -11 )
Hi there!
Let the width of the rectangle be called x. Then the length of the rectangle is 2x. We get the following perimeter:
Collect the terms
Divide by 6
Therefore, the width of the rectangle is 21 feet and the length is 2 × 21 = 42 feet.
