Surface area is the amount of surface that is exposed in a space. For instance, a sheet of flat paper covers the same amount of area as a bigger piece of crumpled up paper, but the bigger piece of paper has more surface area. Folding and crumpling surfaces up makes it easy to fit more surface area into a smaller space.
Since villi are very tiny folds that stick out from the small intestines, more surface area is fit inside a smaller space. If you were to "flatten out" all the little villi of the small intestines it would cover a football field. Not so if the inside of the intestine were smooth.
