Arectangle has vertices at (-1,6), (-1,-2), (3,6), and (3,-2). sara says the area of the rectangle is 16 square units and her
work is shown below
steps
step 1
step 2
step 3
sara's work
base: 113-4
height: 161+f2-4
area: 4x4-16 square units
where, if at all, did sara first make a mistake in finding the area of the rectangle?
step 1
step 2
step 3
no mistake

Step 2

Step-by-step explanation:

Let

Plot the vertices to better understand the problem

see the attached figure

The area of the rectangle is equal to

we have

step 1

Find the base b (BD)

step 1 is correct

step 2

Find the height h (BA)

step 2 is not correct

step 3

Find the area

Therefore

Sara first make a mistake in finding the area of the rectangle in Step 2
