Answer:
a) (3,0)
b)
Step-by-step explanation:
For part a)
Just sketch the coordinates on a piece of paper and map them out i have attached an image the 4th point is (3,0) for the figure to be a rectangle
For part b)
Length is 3 units of the rectangle and breadth is 4 units
so,
Area= Length x Breadth
Area= 3 x 4
Area=12
and Perimeter= Sum of all sides
The rectangle has 2 Lengths and 2 Breadths which means
Perimeter=2L + 2B
Perimeter=2(3)+2(4)
Perimeter=6+8
Perimeter=14
