write your answer as a whole number or a decimal rounded to the nearest hundredth.
square square millimeters

Explanation:

Step1: Calculate area of outer rectangle

$\text{Area}_{\text{outer}} = 69.9 \times 65.7$
$\text{Area}_{\text{outer}} = 4592.43$

Step2: Calculate area of inner rectangle

$\text{Area}_{\text{inner}} = 34.7 \times 32.6$
$\text{Area}_{\text{inner}} = 1131.22$

Step3: Subtract inner from outer area

$\text{Area}_{\text{shaded}} = 4592.43 - 1131.22$
$\text{Area}_{\text{shaded}} = 3461.21$

Answer:

3461.21 square millimeters
