the area of a rectangle is 4 3/8 square feet, and its length is 1 1/4 feet. what is the rectangle's width, in feet

3  1/2 ft

Step-by-step explanation:

lets start by converting our fractions into improper fractions and giving them like denominators

4  3/8=   35/8

1  1/4= 5/4

the biggest like number these denominators fit into is 8

so 35/8 stays the same and

5/4 becomes 10/8

now, area of a rectangle is length x  width= area

so plug in the numbers and solve for x!

10/8  times  x= 35/8

division with fractions doesn't exist, so you flip the fraction and multiply instead.

35/8  x 8/10 = 35/10

simplify and get 3  1/2!

the answer is (4,3)

since the rule for r0, 90º is (-y,x) and it was already applied to form the image, all you have to do is reverse the answer using this formula.
