Answer:
Perimeter will be = 21.6
Step-by-step explanation:
As we know the formula to get the length between two points A and B having coordinates A(x,y) and B (a,b) is
AB = √(x-a)²+(y-b)²
We will use this formula to get the lengths of all sides of the quadrilateral.
AB=√(4+3)²+(2-2)² =√7² =7
BC = √(3-4)²+(-3-2)²=√(-1)²+(-5)² = √1+25=√26 = 5.1
CD = √(3+3)²+(-3-3)² = √6²+(-6)² = √72 = 8.5
DA = √(-3+3)²+(3-2)² =√1 = 1
Since perimeter of the quadrilateral = sum of lengths of all sides
Perimeter = 7 + 5.1 + 8.5 + 1 = 21.6
Answer:
Perimeter of ABCD = 21.58 units
Step-by-step explanation:
Distance formula:-
Le (x₁,y₁) and (x₂,y₂) be the two end points of a line segments.Then length of segment = √[(x₂ - x₁)² + (y₂ - y₁)²]
It is given that,
ABCD is a quadrilateral A(-3,2) B(4,2) C(3,-3) D(-3,3)
To find the side length of quadrilateral
A(-3,2) , B(4,2), C(3,-3) and D(-3,3)
AB = √[(4 --3)² + (2 - 2)²] = √[(4 +3)² + 0] = 7
B(4,2) C(3,-3)
BC = √[(3 - 4)² + (-3 - 2)²] = √26 = 5.1
CD = √[(-3 - 3)² + (3 - -3)²] =√72 = 8.48
AD = √[(-3 - -3)² + (3 - 2)²] =1
To find perimeter of ABCD
Perimeter = AB + BC + CD + AD = 7 + 5.1 + 8.48 + 1= 21.58
