Question

5½ in 6 in. number sentence: 6 × 5½ = 8 area: 8

Explanation:

Step1: Convert mixed number to improper fraction

The length is \( 5\frac{1}{2} \) inches, which is equal to \( \frac{5\times2 + 1}{2}=\frac{11}{2} \) inches.

Step2: Calculate the area

The area of a rectangle is length times width. The width is 6 inches and the length is \( \frac{11}{2} \) inches. So the area is \( 6\times\frac{11}{2} \).
Simplify the calculation: \( 6\times\frac{11}{2}=\frac{6\times11}{2}= 3\times11 = 33 \) square inches.

Answer:

The correct number sentence is \( 6\times5\frac{1}{2}=33 \) and the area is \( 33 \) square inches.
