Question

the area of a rectangular dog pen is 8 1/2 square feet. if the width is 3 2/5, what is the length, in feet?

Answer 1

Answer:

2 1/2 or 2.5

Step-by-step explanation:

The area is the length times the width. To solve for the length, you have this equation using the data you already have. 8 1/2 = 3 2/5 x length. 8 1/2 / 3 2/5 = length. 8.5/3.4 = length. length = 2.5 OR to do this fraction wise, you can make them fractions and divide, making 8/1 -> 16/2 + 1/2 = 17/2 and 3/1 - 15/5 + 2/5 = 17/5 and divide those, which ends up at 2 1/2 but fraction wise makes it more complicated
