Question

the top of a table measure 2 m 25 cm by 1m 20 cm. find the area in square meters.

Answer 1

measure of table top =
2m 25cm × 1m 20cm
or 2.25 m × 1.2 m
therefore area of table top will be
2.25 ×1.2 m²
= 2.7 m²

Answer 2

$\huge\mathsf\purple{\boxed{1 \ m \ = \ 100 \ cm}}$

•°•

$\mathsf{1 \ cm \ = \ 1 \ / \ 100 \ cm}$

$\huge\mathsf{Given \ -}$

$\mathsf{Length \ = \ 2 \ m \ 25 \ cm}$

$\mathsf{25 \ cm \ = \ 25 \ / \ 100 \ cm \ = \ 0.25 \ cm}$

$\textbf{Length = 2 m + 0.25 m = 2.25 m}$


$\mathsf{Breadth \ = \ 1 \ m \ 20 \ cm}$

$\mathsf{20 \ cm \ = \ 20 \ / \ 100 \ cm \ = \ 0.20 \ cm}$

$\textbf{Breadth = 1 m + 0.20 m = 1.20 m}$

$\huge\mathsf\red{Area \ -}$

$\mathsf{= \ Length × Breadth}$

$\mathsf{= \ 2.25 × 1.20}$
