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

answer: yard ramps with a level off platform are typically 36 feet long. truck, rather than at an angle, enabling access to those pallets at the very back of the truck. if you are using your yard ramp to convert a loading dock into a drive-in door, we even at 60 inches (5 feet) high and a 30 foot ramp, the slope of the ramp will be less
