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

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.
