A set is a well-defined collection of objects. Each object in a set is called an element of the set. Two sets are equal if they have exactly the same elements in them.
A set is a subset of another set if all elements of the set are elements of the set . In other words, the set is contained inside the set . The subset relationship is denoted as A ⊂ B .The relationship of one set being a subset of another is also called inclusion or we can say Set B may have more elements than A does.
Option 4 .Set B may have more elements than A does is the right answer.

Length of side of new square is 17 inches
Step-by-step explanation:
- Step 1: Let the length of the side of the old square be x. Then length of side of new square = x + 3 and Perimeter of new square = 40 + 2x
Perimeter of a square = 4 × side
⇒ 4(x + 3) = 40 + 2x
⇒ 4x + 12 = 40 + 2x
⇒ 2x = 28
⇒ x = 14 inches
- Step 2: Find length of side of the new square
⇒ x + 3 = 17 inches
