Question

Which expression does not represent the perimeter of the rectangle?

• A. $4\mathrm{j}\left(60\right)$
• B. $8\mathrm{j}+120$
• C. $2(4\mathrm{j}+60)$
• D. $8(\mathrm{j}+15)$

Answer 1

The correct option is B

$8\mathrm{j}+120$

Given: Length $=4\mathrm{j}$ and breadth $=60$

The perimeter of rectangle $=2(\text{length}+\text{width})$

$$\begin{gathered} =2(4\mathrm{j}+60) \\ =8\mathrm{j}+120 \\ =8\left(\mathrm{j}+15\right) \end{gathered}$$

So, option $\left(\mathrm{B}\right),\left(\mathrm{C}\right)$and $\left(\mathrm{D}\right)$ are correct

Hence, option $\left(\mathrm{A}\right)$ does not represent the perimeter of rectangle.
