Question

The length of each side of a square is $\frac{3x}{4}+1$. What is the perimeter of the square?

• A. $x+1$
• B. $3x+1$
• C. $3x+4$
• D. $\frac{9}{16}{x}^2+\frac{3}{2}x+1$

Answer 1

Answer: (C)

$3x+4$

Length of side of square $=\frac{3x}{4}+1$

Perimeter of a square $=4\times \text{side}$
$=4\times (\frac{3x}{4}+1)$
$=3x+4$

So, perimeter of square with side $(\frac{3x}{4}+1)$ is $(3x+4)$
