Question

Devon's wall has an area of 42 square feet she has a printing that is 10 feet by 3 feet can she have the painting on the wall justify your arguments

Answer 1

Yes because 10*3= 30 which is less than 42

Answer 2

To find the area of a square/rectangle, you multiply the width times the height. To find the area of the printing, you do 10•3 which equals 30 square feet.
That means that the printing will fit on the 42 square feet of wall! It will even have 12 square feet left extra.
