Math Problem Statement

Marisa was finding the area of a rectangle with length 3 2/3 centimeters (cm) and 5 5/8 cm. What is the area of the rectangle?

Solution

The problem is asking to find the area of a rectangle with the given dimensions.

We can break the problem into the two dimensions provided:

  • Length: 3233 \frac{2}{3} cm, which can be written as an improper fraction: 323=1133 \frac{2}{3} = \frac{11}{3}
  • Width: 5585 \frac{5}{8} cm, which can be written as an improper fraction: 558=4585 \frac{5}{8} = \frac{45}{8}

The area AA of a rectangle is calculated by multiplying the length and the width:

A=Length×Width=113×458A = \text{Length} \times \text{Width} = \frac{11}{3} \times \frac{45}{8}

Let's calculate this.The area of the rectangle is 20.625cm220.625 \, \text{cm}^2.

Here are 5 related questions to expand on this problem:

  1. How do you convert a mixed number to an improper fraction?
  2. How is the area of a rectangle derived from its dimensions?
  3. Can you apply the same method to find the area of other geometric shapes?
  4. How can you convert the decimal result back into a fraction if needed?
  5. What is the significance of using units (e.g., cm2^2) in area calculations?

Tip: When multiplying fractions, you can simplify by canceling common factors between the numerator and denominator before multiplying.
