Area = Length x Width (A = LW) Since the length and width of a square are the same, you can use Area = Length2 (A = L2)
Use squares and try it out for yourself. Get a number of squares and make a rectangle 3 squares long by 4 squares wide. Count the squares. You should have 12 squares (or 3*4). That's the best way I know to prove the formula.
The cube is bounded by six equal-sized squares, so the surface area is simply six times one of those squares.
Just add the area of the six squares - that gives you 6a2, where a is the length of one side.
The cube's surface area consists of six squares; you can simply add the area of each of the squares. Note that each of the squares has the same size.
The formula is: A2 - B2 = (A + B) (A - B)

The formula for the area of a square is simply L2 (sometimes referred to as s2 ) where L (s) is the length of one side. The formula for the area of a rectangle is LW, where L is the length and W is the width. The formula for the area of a rectangle can be used to find the area of a square, but the formula for the area of a square cannot be used to find the area of a rectangle. This is because by definition, all squares are rectangles, but not all rectangles are squares.
Squares are rectangles so the formula for area will stay the same.

no,we can divide the figure into squares,rectangles and triangles

With great difficulty! One way would be to overlay a grid of evenly spaced squares (of a known area) and count the number of squares, but this can hardly be called accurate!
It is a formula which is valid only for rectangles (or squares). For all other plane shapes it is wrong.
there is no formula - the answer is 64
Area of one face (one of the squares), squared. If the side is x the area of the surface is x times x times 6.
i think its impossible Here is a way: Construct a number of squares that are one unit in area. For example, if you want to know the area of a plot of land, construct squares that are one square foot each. Then put as many of those squares as possible onto your plot without any gaps or any overlapping. Count the number of squares that you were able to put.
To find the number of squares in an area of 7' x 16', first calculate the total area, which is 112 square feet (7 x 16 = 112). The number of squares depends on the size of the squares you want to fit into that area. For example, if you use 1' x 1' squares, you can fit 112 squares in that area. If the size of the squares changes, the number of squares will also change accordingly.
