20 * 40 = ______ square feet
To find the area of the mirror in square feet, we need to convert the dimensions from inches to feet. Since 1 foot is equal to 12 inches, we can use this conversion factor.
Length in feet = Length in inches / 12
Width in feet = Width in inches / 12
Given that:
Length = 40 inches
Width = 20 inches
Length in feet = 40 / 12 = 3.33 feet (rounded to two decimal places)
Width in feet = 20 / 12 = 1.67 feet (rounded to two decimal places)
Now, to find the area of the mirror in square feet, multiply the length by the width.
Area = Length in feet * Width in feet
Area = 3.33 feet * 1.67 feet
Area ≈ 5.56 square feet (rounded to two decimal places)
Therefore, the approximate area of the mirror is 5.56 square feet.
To find the area of the mirror in square feet, we first need to convert the dimensions from inches to feet.
Since there are 12 inches in a foot, we divide the length by 12 and the width by 12, to get:
Length in feet = 40 inches / 12 = 3.33 feet (rounded to two decimal places)
Width in feet = 20 inches / 12 = 1.67 feet (rounded to two decimal places)
Now, we can find the area by multiplying the length and width together:
Area = Length × Width
Area ≈ 3.33 feet × 1.67 feet
Calculating this, we get:
Area ≈ 5.55 square feet (rounded to two decimal places)
Therefore, the approximate area of the mirror is 5.55 square feet.
