What is the area of a rectangle that has a length of 3 1/5 miles and a width of 5 1/2 miles?
3.2 * 5.5 = ______ sq. miles
To find the area of a rectangle, you need to multiply its length by its width. In this case, the length of the rectangle is 3 1/5 miles, and the width is 5 1/2 miles.
To multiply mixed numbers, you can follow these steps:
1. Convert the mixed numbers to improper fractions.
- 3 1/5 = (3 * 5 + 1) / 5 = 16/5
- 5 1/2 = (5 * 2 + 1) / 2 = 11/2
2. Multiply the improper fractions.
- (16/5) * (11/2) = 176/10
3. Simplify the fraction, if possible.
- Divide both the numerator and denominator by their greatest common divisor, which is 2 in this case.
- 176/10 = (88/2) / (10/2) = 88/5
Therefore, the area of the rectangle is 88/5 square miles.
