Question

find the area of rectangle cdef. round your answer to the nearest tenth if necessary. image of rectangle cdef with side lengths 17.1 in and 7.6 in

Explanation:

Step1: Recall the formula for the area of a rectangle

The area \( A \) of a rectangle is given by the product of its length \( l \) and width \( w \), i.e., \( A = l \times w \).

Step2: Identify the length and width from the diagram

From the diagram, the length \( l = 17.1 \) in and the width \( w = 7.6 \) in.

Step3: Calculate the area

Substitute the values of \( l \) and \( w \) into the formula: \( A = 17.1 \times 7.6 \).
Calculating the product: \( 17.1 \times 7.6 = 129.96 \).

Step4: Round to the nearest tenth (if necessary)

The value \( 129.96 \) rounded to the nearest tenth is \( 130.0 \) (since the hundredth digit is 6, which is greater than or equal to 5, we round up the tenth digit).

Answer:

The area of rectangle CDEF is \( 130.0 \) square inches (or \( 129.96 \) square inches before rounding, but rounded to the nearest tenth is \( 130.0 \)).
