Q. Find the length and width op the quadrilateral with vertices at (6,4),(4,4,(6,7),(4,7).
Identify Coordinates and Plot: Identify the coordinates of the vertices of the quadrilateral and plot them if necessary to understand the shape.Vertices: A(6,4), B(4,4), C(6,7), D(4,7).By looking at the coordinates, we can see that AB and CD are horizontal lines, and AD and BC are vertical lines. This suggests that the quadrilateral is a rectangle.
Calculate Length of AB: Calculate the length of AB. Length AB=x-coordinate of B−x-coordinate of A=4−6=−2. Since length cannot be negative, we take the absolute value. Length AB=∣−2∣=2.
Calculate Length of AD: Calculate the length of AD.Length AD=y-coordinate of D−y-coordinate of A=7−4=3.
Confirm Rectangle Shape: Since AB and CD are parallel and equal in length, and AD and BC are parallel and equal in length, and all angles are right angles, we confirm that the quadrilateral is a rectangle.Therefore, the length of the rectangle is the longer side, and the width is the shorter side.
Determine Length and Width: Determine which side is the length and which is the width.Since AB=2 and AD=3, the length of the rectangle is 3 and the width is 2.
