100 POINTS! Question 1
In a park, a picnic area is surrounded by grass in the shape of a rectangle, as shown in
the diagram below. If the area of the shaded region that represents the grass is 48
square yards, what is the length and width of the picnic area?
1.
How could we wilte an expression to represent the area of the larger rectangle?
I
How could we write an expression to represent the area of the smaller rectangle
3. How could we wilte an expression that only represents the area of the shaded region

Question 2
A family plans to surround their pool with a patio of uniform width , the pool has an area of 150 square feet . The dimensions of the pool would be 15 by 20, find the dimensions

-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
