The intersection of two sets is the set composed by the elements that the two sets have in common.
So, we have
In this particular case, since Y is a subset of X, we have
In fact, all elements of Y are elements of X as well, so in particular they are common elements.
The length of the diagonal of the garden with 19.6 square feet and 4.3 length is : 6.3 feet
<h3>What is a rectangle?</h3>A rectangle is a quadrilateral with four sides and four vertices each of angle 90°.
Analysis:
Area of rectangle: 19.6 square feet
length of one side = 4.3 feet
width of one side = Area/length = 19.6/4.3 = 4.6 feet
the diagonal and width and length of a rectangle for a right angle triangle.
To find the diagonal, we use Pythagoras theorem
=
+
=
+
= 39.7
diagonal = = 6.3 feet
in conclusion, the diagonal of the rectangular garden is 6.3 feet
