Jonathan points on a rectangular canvas that has an area of 3 1/8 square feet. one side of the canvas measurement 2 1/2 feet. what is the measure of the adjacent side?

If you would like to know what is the measure of the adjacent side, you can calculate this using the following steps:

an area = length * width
3 1/8 square feet = 2 1/2 feet * x
3 1/8 = 2 1/2 * x
25/8 = 5/2 * x
x = 25/8 * 2/5
x = 5/4 = 1 1/4 feet

The correct result would be 1 1/4 feet.

3x+9+4x+x=8x+9that's the answer for your question.
