Question

The area of a square is $16c{m}^2$. The area of the rectangle with length equal to double the side of the square and breadth equal to half of the side of the square is ___$c{m}^2$

• A. 12
• B. 16
• C. 26
• D. 32

Answer 1

The correct option is B

16

Area of square = $side\times side=16c{m}^2$
$\Rightarrow$ $4\times 4=16$
$\Rightarrow$ side of square = $4cm$
$\therefore$ Length of rectangle =$2\times 4$ = $8cm$ and
Breadth of rectangle = $0.5\times 4$ = $2cm$
$\therefore$ Area of rectangle = $8\times 2$ = $16c{m}^2$
