A sign is being painted that includes three small squares with a side length of us, and two large wants with it sign length of us right in expression to find the total area of the sign that needs to be painted
The area of each small square is given by:
Area of small square = side length squared
= 4 square units
The area of each large square is also given by:
Area of large square = side length squared
= 9 square units
To find the total area of the sign that needs to be painted, we need to add up the areas of all the squares:
Total area = 3*(area of small square) + 2*(area of large square)
= 3*(4) + 2*(9)
= 12 + 18
= 30 square units
Therefore, the total area of the sign that needs to be painted is 30 square units.
