A sign is being painted that includes 3 small squares with a side length of s and 2 large ones with a side length of S. write an expression to find the total area of the sign that needs to be panted
The total area of the sign that needs to be painted is equal to the sum of the areas of the 3 small squares and the 2 large squares.
Area of one small square: s^2
Area of 3 small squares: 3s^2
Area of one large square: S^2
Area of 2 large squares: 2S^2
Therefore, the expression for the total area of the sign that needs to be painted is:
3s^2 + 2S^2
