Question

A square with a side of $3$ cm and a rectangle with a width of $3$ cm have the same area. What's the length of the rectangle?

• A. $2$ cm
• B. $1$ cm
• C. $3$ cm
• D. $4$ cm

Answer 1

Answer: (C)

$3$ cm

The area of the square is $3\times 3=9c{m}^2$
The area of the rectangle is given by $l\times b$

Thus $l\times b=9c{m}^2$

$\to l=\frac{9}{3}$ where $b=3cm$ is given
Thus, $l=\frac{9}{3}=3$ cm
