Final answer:
To find the area of a rectangular board that measures 30 by 6 inches, multiply the length by the width to get 180 square inches.
Step-by-step explanation:
To calculate the area of a rectangular board with dimensions of 30 by 6 inches, you would simply multiply the length (30 inches) by the width (6 inches). The formula for the area of a rectangle is:
Area = length × width
So, in this case, it would be:
Area = 30 in × 6 in
= 180 in²
The area of the rectangular board is 180 square inches.
