Method 1.
Look at the picture 1.
We have:

ΔLOM and ΔMON are isosceles triangles. Therefore the two angles opposite the legs are equal.
The sum of the internal angles in each triangle is 180°. Thereofre in ΔLMN we have:
Area = length x width
323 = 19 x w
323 = 19w
Divide both sides by 19
<u>323</u> = <u>19</u> w
19 19
w = 17 feet

Degree is the power of the biggest term( Here 7x5)
<span>First we have to find the factors of 144. 144 = 2 * 2 * 2 * 2 * 3 * 3. Then we will find the pairs of numbers which product is 144. 1 * 144 = 144, 2 * 72 = 144, 3 * 48 = 144, 4 * 36 = 144, 6 * 24 = 144, 8 * 18 = 144, 9 * 16 = 144. And because of the commutative property of multiplication: 16 * 9 = 144, 18 * 8 = 144, 24 * 6 = 144, 36 * 4 = 144, 48 * 3 = 144, 48 * 3 = 144, 72 * 2 = 144 and 144 * 1 = 144. </span>
