Find the area of a rectangle whose vertices are ( 2/5, 2) , (2/5, -1) , (0,2) and ( 0,-1)

Question

Hi, my book is saying the answer is 6/5. I keep getting something else and i remember my teaching saying there are errors in the book so I don't know if my answer is right or wrong. 

 

I used the distance formula to solve and then multiplied for length and width. 

Answer 1

Plot the four points.

The height of the rectangle is 3.

The width of the rectangle is 2/5

 

A = (2/5)(3)

A = 6/5
