Quizplus · Accepted Answer

To find the perimeter of a rectangle, use the formula $2 \times (\text{length} + \text{width})$. Here, the length is $7 \frac{1}{2}$ inches and the width is $5 \frac{1}{4}$ inches. Convert these to improper fractions: $7 \frac{1}{2} = \frac{15}{2}$ and $5 \frac{1}{4} = \frac{21}{4}$. Add them: $\frac{15}{2} + \frac{21}{4} = \frac{30}{4} + \frac{21}{4} = \frac{51}{4}$. Multiply by 2 for the perimeter: $2 \times \frac{51}{4} = \frac{102}{4} = 25 \frac{1}{2}$ inches.
