Quadrilateral WXYZ has vertices w(2.10), x(10,10), y(10,2), and z(2,2). Determine if quadrilateral is a rhombus.

a. No, quadrilateral WXYZ is not a rhombus.
b. Yes, quadrilateral WXYZ is a rhombus because the sides are perpendicular
c. Yes, quadrilateral WXYZ is a rhombus because the slopes of the diagonals are perpendicular.
d. There is not enough information to determine.

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.

the answer is  

a.

28 ft2
