Area of a rhombus = 1/2 x diagonal 1 x diagonal 2
= 1/2 x 15 1/2 x 13 1/5
= 1/2 x 31/2 x 66/5
=31/2 x 33/5
= 1023/10
= 102.3
Final Answer: 102.3 square feet
Y= 4 - 4/5x all you have to do is make it go up 4 from 0 and either go down 4 and go right 5 or up 4 and to the left 5... hope this helped!
The polygon is a perfect square. I graphed those points on a graph. I hope this helped if not let me know so I can try and write the correct answer.
