Directions

Tita wants to decorate the kitchen with new wallpaper, but she can’t count every square unit on the walls like she did with the tile.

To find the area, she needs to multiply the length by the width of the surface she will cover.

Area = length × width

Also written as :

A = l × w

One wall is a rectangle that is 10 feet long by 8 feet wide. How much wallpaper will Tita need to cover it?
