Answer 1

$\huge{ \underline{ \tt{Question \: : }}}$

Find the area of a rectangle in metre if length is 2 m 20 cm and breadth is 4m.

$\huge{ \underline{ \underline{ \tt{Solution \: : }}}}$

• Length = 2m 20cm
• Breadth = 4m

As we know, the area of a rectangle

$\boxed{ \bf{area = length \times breadth}}$

$\tt \to2m \: 20cm \times 4m$

As we know,

$\boxed{ \bf{1m = 100cm}}$

$\tt \therefore20cm = \frac{20}{100} m = 0.2m$

$\tt \to(2m + 0.2m) \times 4m$

$\tt \to2.2m \times 4m$

$\tt \to(2.2 \times 4) {m}^{2}$

$\tt \to8.8 {m}^{2}$

Therefore, the area of the rectangle is 8.8m2
