Step-by-step explanation:
A quadrilateral is a closed figure with four sides and four vertices. The vertex is a point where line segments meet. The points where the sides of a quadrilateral meet are called the vertices (which is the plural form of "vertex"). The prefix “quad” means four. You can always remember that a quadrilateral is a four sided figure because of this prefix.

= 4/ 2*3
= 2/3
88.3 is what % of 21
21 × a percent = 88.3
Divide 21 on either sides to find the percentage.
