Answer:
Set; subset.
Step-by-step explanation:
A group of objects or numbers is called a set while a part of a set is called a subset. The objects or numbers that make up a set are generally referred to as elements or members and are written inside a pair of curly braces {}.
A set can be made up of elements such as numbers, alphabets, people, cars etc.
<em>For instance, Set A = {2, 4, 6, 8, 10, 12} represents all the even number between 1 - 12.</em>
On the other hand, a subset is a part of a larger set.
<em>For instance, comedy movies, horror movies, romance movies, action movies are a subset of movies. </em>

The answer is <span>length = 10 yd, width = 2 yd
proof
</span><span>The length of the playground is 5 times longer than its width, it means
l=5w, but 10= 2x5 so we can write l= 5w,
and Area = 20 =l x w = (5x2) x 2 =20</span>
