Question

Figure A has a perimeter of 48 m and one of theside lengths is 18 m. Figure B has a perimeter of 80 m.What is the corresponding side length of Figure B?

Answer 1

We have to use proportions to solve this question.

According to the given information, the perimeter of Figure A is to the sidelength of that figure as the perimeter of Figure B is to the sidelength of that figure:

`\begin{gathered} (48)/(18)=(80)/(x) \\ x=(80\cdot18)/(48) \\ x=30 \end{gathered}`

The corresponding sidelength of Figure B is 30.
