Given: Area of the a square wall = 256 inches squared(it must be squared since we are talking about the area)
Formula for Area of Square wall: A=l^2, where l is the length of one side of a square, since all lengths in the square is equal.
Since we only the area is given, in order to find for l, we must equate the formula to the value of l.
A=l^2
Take the square root of both sides in order to cancel out l^2
l=√A
Equation:
l=√256
l=16 inches
The length of the lights from each side of the wall is 16 inches.
To cover the whole square wall, we multiply 1 side by 4, since the measurement of 1 side is similar with all 4 sides.
16x4=64 inches
The lights need to be 64 inches if it needs to cover all the way around the wall.
