Question

edward’s grandmother used to make him pannukakku when he was little. he wants to surprise her by making it himself. the recipe he found requires a 9-in. by 13-in. rectangular pan. edward would like to use a round cast iron pan like his grandmother does.

what is the area of a 9-in. by 13-in. pan?

Explanation:

Step1: Recall the area formula for a rectangle

The area \( A \) of a rectangle is given by the formula \( A = \text{length} \times \text{width} \).

Step2: Identify the length and width

Here, the length is \( 13 \) inches and the width is \( 9 \) inches.

Step3: Calculate the area

Substitute the values into the formula: \( A = 13 \times 9 \).
\( 13 \times 9 = 117 \) square inches.

Answer:

\( 117 \text{ in.}^2 \) (corresponding to the option "117 in.²")
