Let one length be x and the other be y

x + x + y + y = 440
2x + 2y = 440

Divide by 2 through ...
x + y = 220
y = 220 - x

Area = xy
Area = x(220 -x) = 220x - $x^{2}$

Given that that max length of x will be -b/2a
a = -1 b = 220
x = $\frac{-220}{-2}$ = 110

x = 110
y = 220 - 110 = 110

Therefore max area = 110 x 110 = 12100 square yards

What is the answer for this problem in the picture

DENIUS [597]

<u>Answer:</u>

The correct answer option is $= 8 x ^ 4 y z ^ 4 \sqrt{2yz}$ .

<u>Step-by-step explanation:</u>

We are given the following expression and we are to simplify it and determine whether which of the given expressions is equivalent to it, assuming $y\geq 0$ and $z\geq 0$ :

$\sqrt { 128 x ^ 8 y ^ 3 z ^ 9 }$

Breaking the terms to get:

$\sqrt { 128 x ^ 8 y ^ 3 z ^ 9 }$ $=8\sqrt{2yz} \times x^{8\times\frac{1}{2} } \times y^{2\times \frac{1}{2} } \times z^{8\times \frac{1}{2} }$

$= 8 x ^ 4 y z ^ 4 \sqrt{2yz}$
