A quadrilateral is formed by the points (0,0) and (5,10) and (10,15) and (5,5)

Calculate the perimeter and area of ABCD and determine if it is a parallelogram

Calculate the distance AB between (0,0) and (5,10)

AB = Square Root((x

AB = Square Root((5 - 0)

AB = Square Root((5

AB = √(25 + 100)

AB = √125

AB = 1

Calculate the distance BC between (5,10) and (10,15)

BC = Square Root((x

BC = Square Root((10 - 5)

BC = Square Root((5

BC = √(25 + 25)

BC = √50

BC = 7.5

Calculate the distance CD between (10,15) and (5,5)

CD = Square Root((x

CD = Square Root((5 - 10)

CD = Square Root((-5

CD = √(25 + 100)

CD = √125

CD = 1

Calculate the distance AD between (0,0) and (5,5)

AD = Square Root((x

AD = Square Root((5 - 0)

AD = Square Root((5

AD = √(25 + 25)

AD = √50

AD = 7.5

Perimeter of ABCD = AB + BC + CD + AD

Perimeter of ABCD = 1 + 7.5 + 1 + 7.5

Perimeter of ABCD =

s = | Perimeter |

s =

A = √(s - a)(s - b)(s - c)(s - d)

A = √(18. - )(18. - )(18. - )(18. - )

A = √(18.)(18.)(18.)(18.)

A = √(1

A =
