subtract the 26 1/2 from 76 and then divide by 2
76-26 1/2 = 49 1/2 / 2 = 24 3/4
* <em>L is the Length</em><em /> <em>and A is the Area
</em><em />
L * L = A
L * L = 1600
L^2 = 1600
√L^2 = √1600
L = 40 feet
Answer: The length of each side is 40 feet.
Btw: <em />this was your question "<em>A square garden has an area of 1600 feet length of each side"</em>
When it should be . . .
<em>"A square garden has an area of 1600 feet squared length of each side"</em>
The charge should be $6. I believe I set this up correctly; let me know if there are any errors. Hope this is helpful & accurate.
3x^2-18+5=47
3x^2 = 60
x^2 = 20
x = 4.472 , x = - 4.472
