What is the dimension ?

Question

3inches is the width 70 is the area of the rectangle

Answer 1

Hi Amari,

A great place to start is with the equation (that's half the battle). The area of a rectangle is A = l * w (area equals length times width). Also, a good grid to work with is, What do I know? What do I need to know? You know the width (3 inches) and the area (70 inches), and you need to know the length, so next you can plug what you know into the formula to find what you need to know. Like this:

A = l * w

70 = l * 3 (or 3l). Next, divide by three on both sides to get length (l) by itself.

l = 70/3 or l = 23.3 (repeating)

If this was helpful, please let me know. Please keep me in mind for any future tutoring needs :)!

Best,

Cliff W.

Answer 2

Divide the area by the width to get the length.

Answer 3

Hi Amari. Since the area of a rectangle is length times with, we can say 70 = 3 times the length. The length is 70/3, or 23 1/3. The perimeter would be 23 1/3 + 23 1/3 + 3 + 3 = 52 2/3.
