Plane A has just 1 ton of fuel left and has requested plane B to refuel it. Plane B has 21 tons of fuel. Fuel transfer happens a
t the rate of 1 ton per minute. Use this information as you work through the activity and find how long it will take to refuel plane A until both planes have the same amount of fuel. Let x be the time in minutes and y be the amount of fuel in tons. The equation y=x+1 represents the quality of fuel with respect to time in plane A, and y=-x+21 represents the quality of fuel with respect to time in plane B. For each equation, find two points that satisfy the equation.

Answer:
B'(3, 5)
Step-by-step explanation:
Rule for the translation of a point (x, y) by 'h' units left and 'k' units upwards,
(x, y) → (x - h, y + k)
If h = 4 and k = 3,
Following this rule coordinates of the image point of B will be,
B(7, 2) → B'(7 - 4, 2 + 3)
→ B'(3, 5)
Therefore, coordinates of the image point B' will be,
B'(3, 5)
First we have to find length of 1 side of the square. We can use formula for area of the square. A=a*a ==> 
where a is length of the side.
From this formula we can find
a=
Now we just have to multiply it by 4, because there are 4 sides.
81*4=324 - its the answer
