Find the area.
A rectangle with sides of lengths 4/5 foot and 1/2 foot
A = lw
Easy way to solve:
A = 0.8 * 0.5
A = 0.4 or 2/5 square feet
To find the area of a rectangle, we multiply the lengths of its sides. In this case, the rectangle has sides of lengths 4/5 foot and 1/2 foot.
To get the area, we can use the formula:
Area = length × width
Plugging in the values, we have:
Area = (4/5) foot × (1/2) foot
To multiply fractions, we multiply the numerators together to get the new numerator and multiply the denominators together to get the new denominator. Therefore, we have:
Area = (4/5) × (1/2) = (4 × 1)/(5 × 2) = 4/10
Now, since 4/10 can be simplified, we divide both the numerator and denominator by their greatest common divisor, which is 2:
Area = (4/10)/(2/2) = (4/10) × (2/2) = (2/5) × 1 = 2/5
Hence, the area of the rectangle is 2/5 square foot.
