Answer:
225 m²
Step-by-step explanation:
If W is the width of the rectangle, and L is the length, then:
60 = 2W + 2L
A = WL
Use the first equation to solve for one of the variables:
30 = W + L
L = 30 − W
Substitute into the second equation:
A = W (30 − W)
A = 30W − W²
This is a parabola, so we can find the vertex using the formula x = -b/(2a).
W = -30 / (2 × -1)
W = 15
Or, we can use calculus:
dA/dW = 30 − 2W
0 = 30 − 2W
W = 15
Solving for L:
L = 30 − W
L = 15
So the maximum area is:
A = WL
A = (15)(15)
A = 225
I’m gonna say no since it’s 5.74 and it isn’t repeating
Can you be more specific? I need a question and I need a close up ! Lol but I’m trying to help.
Answer:82
Step-by-step explanation: the patch of grass is a 2 by 2 first find the area which is 4
then find the area of the garden forget the grass patch for now 8 x 11= 88 now 88 - 4 = 82ft
Answer:
$17
Step-by-step explanation:
Think about it like this.
$4.25 is equal to 0.25 * x value, where x is the weekly allowance
$4.25=0.25x
$17=x
