A square has sides of length (2a-b) metre. Write out a formula for its area
The formula for the area of a square is given by:
Area = (side length)^2
So, the formula for the area of a square with sides of length (2a-b) metres is:
Area = (2a-b)^2
Expanding this expression:
Area = 4a^2 - 4ab + b^2
Therefore, the formula for the area of the square is:
Area = 4a^2 - 4ab + b^2
