Answer:
<em>Gardener will need 4 more plants.</em>
Step-by-step explanation:
Gardener has 780 plants and wants to plant them in an array of n rows and n columns.
The number of plants needed to do that is:
He actually has 780 plants, thus it should occur:
Taking the square root:
n=27.9
Since n needs to be an integer, we round up n to get
n=28
But 
, 4 more than the actual number of plants, thus:
Gardener will need 4 more plants.
Note: There are other possible results for n. If we set n=29, then 
and Gardener would need 841-780=61 more plants, but the question asked for the minimum number of plants.

Answer:
The area is 84. The missing side is 7.
Step-by-step explanation:
Okay so perimeter = length+length+width+width right? If 12 is the length, then 12+12=24, which is the length part of perimeter. 38-24=14 and 14/2=7. The missing side is 7 because 12+12+7+7=38 and the area is 84 because 12x7=84. Good luck!
