Answer:

60 square foot

Step-by-step explanation:

Perimeter of a rectangular garden = 58 foot

Let x and y denote length and width of the rectangular garden.

2 (Length + Width) = Perimeter of the rectangular garden

2(x+y)=58\\x+y=\frac{58}{2}\\ x+y=29

So,

length = x

width = y = 29-x

The length is reduced by 7 feet and the width becomes half.

New length = x-7

New width = \frac{1}{2}(29-x)

New perimeter = 34 foot

2[(x-7)+\frac{1}{2}(29-x)]=34\\ 2[2(x-7)+(29-x)]=2(34)\\2(x-7)+(29-x)=34\\2x-14+29-x=34\\2x-x-14+29=34\\x+15=34\\x=34-15\\x=19

So,

New length =x-7=19-7=12\,\,foot

New width = \frac{1}{2}(29-19)=\frac{1}{2}(10)=5\,\,foot

Area of the new smaller garden = New length × New Width

= 12 × 5

= 60 square foot

Taylor bought 200 shares of stock for $18.12 per share last year. He paid his broker a flat fee of $30. He sold te stock this mo
rusak2 [61]
The answer is $3990 heres why

First you need to find out what is the total you paied for the shares
$18.12x200= $3624

Then you need to add the flat fee to the spending chost
$3624+$30= $3654 

Now you re-mulitply the chost per stock to the tootle #'s of stock you sold
$21x200= $4200

Then you need to find out what how much you need to pay the stock broker
$4200x.05= $210
 
Then once you find out how much you need to pay him subtract that amount to the total money earned from selling your stocks
$4200-$210= $3990 

Then if you want to also find out your profit just subtract the total amount you payed for the stock and subtract it from the total amount you gained from the stock. 
$3990- $3654= $336 Profit
