Q. The area of a rectangle is 1414 square units. It has side lengths xx and yy. Given each value for xx, find yy. \newline a. x=213x=2\frac{1}{3} \newline b. x=415x=4\frac{1}{5} \newline c. x=76x=\frac{7}{6}
  1. Area Formula: The area of a rectangle is given by the formula A=x×yA = x \times y, where AA is the area, xx is one side length, and yy is the other side length. We are given that A=14A = 14 square units.
  2. Calculate yy for aa. For aa when x=73x = \frac{7}{3}, we can find yy by rearranging the area formula to y=Axy = \frac{A}{x}. So y=1473y = \frac{14}{\frac{7}{3}}.
  3. Calculate yy for b.b.: Calculating yy for a.a., we get y=14(73)=14×(37)=6y = \frac{14}{\left(\frac{7}{3}\right)} = 14 \times \left(\frac{3}{7}\right) = 6. So when x=(73)x = \left(\frac{7}{3}\right), y=6y = 6.
  4. Calculate yy for cc: For bb when x=215x = \frac{21}{5}, we find yy by using the formula y=Axy = \frac{A}{x} again. So y=14(215)y = \frac{14}{\left(\frac{21}{5}\right)}.
  5. Calculate yy for cc: For bb when x=(21/5)x = (21/5), we find yy by using the formula y=A/xy = A / x again. So y=14/(21/5)y = 14 / (21/5).Calculating yy for bb, we get y=14/(21/5)=14×(5/21)=10/3y = 14 / (21/5) = 14 \times (5/21) = 10/3. So when x=(21/5)x = (21/5), cc11.
  6. Calculate y for c.: For b. when x=215x = \frac{21}{5}, we find y by using the formula y=Axy = \frac{A}{x} again. So y=14215y = \frac{14}{\frac{21}{5}}.Calculating y for b., we get y=14215=14×521=103y = \frac{14}{\frac{21}{5}} = 14 \times \frac{5}{21} = \frac{10}{3}. So when x=215x = \frac{21}{5}, y=103y = \frac{10}{3}.For c. when x=76x = \frac{7}{6}, we find y by using the formula y=Axy = \frac{A}{x} again. So y=1476y = \frac{14}{\frac{7}{6}}.
  7. Calculate yy for cc. For bb. when x=215x = \frac{21}{5}, we find yy by using the formula y=Axy = \frac{A}{x} again. So y=14215y = \frac{14}{\frac{21}{5}}.Calculating yy for bb., we get y=14215=14×521=103y = \frac{14}{\frac{21}{5}} = 14 \times \frac{5}{21} = \frac{10}{3}. So when x=215x = \frac{21}{5}, cc11.For cc. when cc33, we find yy by using the formula y=Axy = \frac{A}{x} again. So cc66.Calculating yy for cc., we get cc99. So when cc33, bb11.
