Question

The area of a particular rectangle is $72$. If the length of the rectangle is twice the width, calculate the width of the rectangle.

• A. $6$
• B. $8$
• C. $10$
• D. $12$
• E. $16$

Answer 1

Answer: (A)

$6$

Area of particular rectangle is given $72$
Let width be $x$ and length be $2x$ as its twice the width.
Formula for area of rectangle is $=$ length $\times$ width
$2x\times x=72$
${2x}^2=72$
$x^2=36$
$x=6$
So width of the rectangle is $6$.
