Question

Medina creates a hopscotch grid of length $4.2\text{m}$, and width $2.45\text{m}$. The total area covered by the hopscotch grid is ${\text{m}}^2$.

• A. 102.9
• B. 9.29
• C. 10.29
• D. 12.09

Answer 1

The correct option is C 10.29

Length of hopscotch grid $=4.2\text{m}$
Width of hopscotch grid $=2.45\text{m}$
The total area covered by the hopscotch grid is $4.2\text{m}\times 2.45\text{m}$
$\Rightarrow$ $4.2\text{m}\times 2.45\text{m}=\frac{42}{10}\times \frac{245}{100}$

$=\frac{10290}{1000}=10.290{\text{m}}^2$
