What is the perimeter of quadrilateral abcd? a(-3,2) b(4,2) c(3,-3) d(-3,3)

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

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

b. astronomers

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers
