What is the area of a quadrilateral with vertices at (1 ,-1), (5 ,-1), (1, 5), (5, 5)?

i think is 3 and 6. this took me 10 min to think.hope to and hope that my answer is brainliest.(follow me )

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.

the one below it is a function
