Extended-response test anwer key. 1. a surveyor is surveying a conservation area. a. a rectangular wetland conservation area is 5.25 miles by 4.8 miles. estimate the area of the park. use a = ℓw. explain each step. b. explain how to multiply decimals. use the dimensions in part a to find the area of the conservation area. c. explain how to divide decimals. then divide to find the length of a rectangular lot that is 1.6 miles wide and has an area of 2.8 square miles.

2 is the final ! : )

-3

step-by-step explanation:

a drawing really does here:

so i draw the horizontal line y=2 and the vertical line x=-2 at this intersection i put b (this is where my right angle is going to be).   so point b is at (-2,2).   point a is 5 units long and is also on y=2 so this point has to be (3,2) or (-7,2) -doesn't matter i will go with (3,2).

now we know c is at (-2,y) we don't know the y yet bet we know that c is on x=-2.

we have the area of the triangle is .5bh=12.5

we know the base length is 5 (ab)

we have the height is (2-y) if you look at your

plug in

.5(5)(2-y)=12.5

solve for y to get the y-coordinate for c

2.5(2-y)=12.5

divide both sides by 2.5 giving:

2-y=5

now subtract 2 on both sides

-y=3

y=-3
