34.5 in
39.7 in
22.2 in
22.3 in
write your answer as a whole number or a decimal rounded to the nearest hundredth.
____ square inches

Explanation:

Step1: Calculate area of outer rectangle

$A_{outer} = 34.5 \times 39.7$
$A_{outer} = 1369.65$

Step2: Calculate area of inner rectangle

$A_{inner} = 22.3 \times 22.2$
$A_{inner} = 495.06$

Step3: Subtract inner from outer area

$A_{shaded} = 1369.65 - 495.06$
$A_{shaded} = 874.59$

Answer:

874.59 square inches
