The side length of a square is 6 cm. If you increase the side length by x cm, the area will increase______ Square centimeter
(6 + x) × (6 + x) - 6 × 6, = 36 + 6x + 6x + x2-36, = 12x + X2 (square centimeter), so the answer is: 12x + x2
If a square increases the length of its opposite sides by 8.5 cm, its area will increase by 102 square cm?
102 / 8.5 = 12 cm
12 * 12 = 144 square centimeters
The side length of a square is increased by 6cm, and the area is increased by 132 square centimeters
(132-6 × 6) / (2 × 6) = 96 / 12 = 8 (CM)
Using the equation solution, this formula is only a deformation of the equation
Let the original length of the square be x cm
(X+6)*（X+6）-X*X=132
The solution is: x = 8
You can change your formula from the solution project, X * x + 12x + 36-x * x = 132
want a go.

The side length of the first square is 3cm longer than that of the second one. The area of the first square is 57cm larger than that of the second one. Find the area of each square
Let the length of the second square be X
(x+3)^2-x^2=57
X ^ 2 = 64M ^ 2 second area
(8 + 3) ^ 2 = the first area of 121m ^ 2
