Question

4. The perimeter and the area of a rectangle are the same. If the length of the rectangle is 4 units, what is the width in units of the rectangle? Round to the nearest WHOLE number.

Answer 1

`\begin{gathered} \text{Let's the width of the rectangle is }x. \\ Perimeter\text{ of rectangle is,} \\ \text{perimeter}=2(x+4) \\ \text{Area of rectangle is,} \\ \text{Area}=4x \\ \text{Now, perimeter and area both are equal,} \\ so, \\ 4x=2(x+4) \\ 4x=2x+8 \\ 4x-2x=8 \\ 2x=8 \\ x=4 \end{gathered}`

So, the width is also 4 unit.
