Answer:
2) ABCD is a RECTANGLE.
Perimeter = 30 units
Step-by-step explanation:
Here, the given points of the quadrilateral are:
A(6, –4), B(11, –4), C(11, 6), D(6, 6)
Now, if P(a,b) and Q(c,d) are any two given points, then the distance between them is given by DISTANCE FORMULA as:
Use this to find the length of all 4 sides:
AB with coordinates A(6, –4), B(11, –4) is given as:
⇒ AB = 5 units
BC with coordinates B(11, –4), C(11, 6) is given as:
⇒ BC = 10 units
CD with coordinates C(11, 6), D(6, 6) is given as:
⇒ CD = 5 units
AD with coordinates A(6, –4),D(6, 6) is given as:
⇒ AD = 10 units
Now, here AB = CD = 5 units, AD = BC = 10 units
Also, in a RECTANGLE, OPPOSITE SIDES ARE EQUAL IN LENGTH.
Hence, ABCD is a RECTANGLE.
Perimeter = AB + BC+ CD + AD = 5 + 10 + 5 + 10 = 30 units
