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
painted.
The total area of the sign that needs to be painted is determined by the sum of the areas of all the squares on the sign.
The area of each small square is given by s^2.
There are 3 small squares, so the total area of the small squares is 3 * s^2.
The area of each large square is given by S^2.
There are 2 large squares, so the total area of the large squares is 2 * S^2.
Therefore, the expression to find the total area of the sign that needs to be painted is 3 * s^2 + 2 * S^2.
