Question 104812This question is from textbook connected mathematics 2
: this is a 5 part question
a. make drawings of at least three rectangle with an area of 300 square feet.
b. what is the width of a rectangle with an area of 300 square feet if its length is 1 foot? if its length is 2 feet? if its length is 3 feet?
c.what is the width of a rectangle with an area of 300 square feet and a length of L feet?
d. how does the width of rectangle change if the length increases, but the area remains 300 square feet?
e. make a graph of (width,length) pairs for a rectangle that give an area of 300 squae feet. explain how your graph illustrates your answer for part (d).

Answer by cheesey(22)   (Show Source):
You can put this solution on YOUR website! Area of a rectangle = width x length
a) thus w x l = 300 ft. draw three rectangles with width and height combinations that equal 300. For example w=30 ft, l = 10 ft.
b) from equation above, if I solve for w, then w = 300/length,
c) use equation in b, substituting L for l.
d) what happens to Area/Length = Width if you increase length? Think about a fraction when you increase the denominator, what happens to the fraction.
e) create a graph using width as your x coordinate and length as your y coordinate. pick some values of each that when multiplied gives 300. I gave you one in part a (30, 10).
