The length of a rectangle is 7.5 cm and its breadth is 2.5 cm. What is the area of the rectangle?

Length of the rectangle = 7.5 cm

Breadth of the rectangle = 2.5 cm

Therefore, area of the rectangle $=$ Length$\times$Breadth

$=7.5\times 2.5$

$=\frac{75}{10}\times \frac{25}{10}$

$=\frac{75\times 25}{100}$

$=\frac{1875}{100}$

$=18.75 {\mathrm{cm}}^2$
