Question
A science fair poster is a rectangle 48 in long and 36 in wide. Some of the entry rules for the fair refer to the area of the poster in square feet. Use the facts to find its area in square feet.
Solution
To find the area of the rectangle in square feet, we first need to convert the dimensions from inches to feet.
Step 1: Convert the dimensions from inches to feet. There are 12 inches in a foot. So, to convert inches to feet, we divide the number of inches by 12.
48 inches = 48/12 = 4 feet 36 inches = 36/12 = 3 feet
Step 2: Calculate the area of the rectangle. The formula for the area of a rectangle is length times width.
So, the area of the poster is 4 feet * 3 feet = 12 square feet.
