Math Problem Statement

What is the area of a rectangle if the width is 2/9 inches and the length is 6/10 inches?

Solution

To find the area of a rectangle, you multiply the width by the length.

Given:

  • Width = 29\frac{2}{9} inches
  • Length = 610\frac{6}{10} inches

The area AA of the rectangle is calculated as:

A=Width×Length=29×610A = \text{Width} \times \text{Length} = \frac{2}{9} \times \frac{6}{10}

Multiply the numerators together and the denominators together:

A=2×69×10=1290A = \frac{2 \times 6}{9 \times 10} = \frac{12}{90}

Now, simplify the fraction 1290\frac{12}{90}:

1290=2×62×45=645\frac{12}{90} = \frac{2 \times 6}{2 \times 45} = \frac{6}{45}

Simplify further by dividing both the numerator and the denominator by 3:

645=215\frac{6}{45} = \frac{2}{15}

So, the area of the rectangle is 215\frac{2}{15} square inches.
