Answer:
35 pounds of tea for 80 cents.
Step-by-step explanation:
Equation::
value + value = value
80x + 60(50-x) = 74*50
80x + 60*50 - 60x = 74*50
20x = 14*50
x = 35 lbs (amt. of 80 cent tea to use)
50-x = 15 lbs (amt. of 60 cent tean to use)
I'm fairly certain that using that wire you can have the same area no matter what dimensions there are, but if you do the square root, or

of 19,001,900 then you get 4359.11688. So your dimensions are
4359.11688 x 4359.11688. To get area, do length x width to get <span>

.
Hope this helped! If it did, please give me a good rating and mark me brainiest.<span /></span>

Hope this helps! :)
