Area is calculated as length times width. A = lw Is the area and length are known, then you can plug in their values and isolate w to find the width. I find it easiest to convert to decimals rather than using mixed numbers. <span>8 ¾ = 8.75 (area) </span><span>3 ½ = 3.5 (length) Now let's plug in the values. 8.75 = 3.5w To isolate w, just divide both sides by 3.5. 8.75 / 3.5 = 2.5 This means w = 2.5. So the width is 2.5 feet. Now convert the decimal back to a mixed number. 2.5 = 2 </span>½
So the answer to this question is that the width is 2.5, or 2 ½.
