Answer:
6 in
Step-by-step explanation:
The <em>area</em> of a picture <em>is</em> 25 7/5 square inches. If the width of the picture is 4 1/2 inches, what is the length? <em>(A=(w)(l) </em>)
Assuming that your "25 7/5 square inches" is not a mistake, then this is equivalent to 26 2/5 square inches.
Converting 26 2/5 sq. in. to an improper fraction, we get 132/5 sq. in., which represents the area of the picture. If the width is 4 1/2 inches, or 9/2 inches, then the length, l, is:
132/5 in^2
l = ------------------
9/2 in
To divide 132/5 in^2 by the fraction 9/2 in, invert 9/2 and multiply:
135 in^2 2
l = -------------- * ------ = 270/9 in = 30/5 in = 6 in
5 9
Using the Pythagorean theorem we can solve for x.
x^2 + 6^2 = 10^2
Simplify:
x^2 + 36 = 100
Subtract 36 from both sides:
x^2 = 64
x = √64
x = 8
